Completing the square is a method used to solve a quadratic function. This is a handy method when there are two instances of the same variable in the function.

Using the quadratic equation formula is a method of solving quadratic equations.

A Java method is a sequence of statements. It is comparable to a function, subroutine, or procedure in other languages.

A method is a group of commands that are executed when you invoke, or call, the method. It is often called a "function", a "procedure", a "subroutine" in other languages; but in OOP environments, the name "method" is used instead.

Least Squares method

By knowing how to use the quadratic equation formula.

In an Object Oriented Programming (OOP) language like Java, it is called a method. In a procedural language (like QBASIC or PHP) it is called a function. They are the same thing. Most people use them interchangeably. -DJ Craig A function returns a value and method does not return a value. A function that doesn't return a value is called (procedure / subroutine)

There are 5 existing methods in solving quadratic equations. For the first 4 methods (quadratic formula, factoring, graphing, completing the square) you can easily find them in algebra books. I would like to explain here the new one, the Diagonal Sum Method, recently presented in book titled:"New methods for solving quadratic equations and inequalities" (Trafford 2009). It directly gives the 2 roots in the form of 2 fractions, without having to factor the equation. The innovative concept of the method is finding 2 fractions knowing their Sum (-b/a) and their Product (c/a). It is very fast, convenient and is applicable whenever the given quadratic equation is factorable. In general, it is hard to tell in advance if a given quadratic equation can be factored. However, if this new method fails to find the answer, then we can conclude that the equation can not be factored, and consequently, the quadratic formula must be used. This new method can replace the trial-and-error factoring method since it is faster, more convenient, with fewer permutations and fewer trials.

There is a new method, called Diagonal Sum Method, that quickly and directly give the 2 roots without having to factor the equation. The innovative concept of this method is finding 2 fractions knowing their sum (-b/a) and their product (c/a). It is fast, convenient and is applicable to any quadratic equation in standard form ax^2 + bx + c = 0, whenever it can be factored. If it fails to find answer, then the equation is not factorable, and consequently, the quadratic formula must be used. So, I advise you to proceed solving any quadratic equation in 2 steps. First, find out if the equation can be factored? How?. Use this new method to solve it. It usually takes fewer than 3 trials. If its fails then use the quadratic formula to solve it in the second step. See book titled:" New methods for solving quadratic equations and inequalities" (Trafford Publishing 2009)

A function is a type of procedure which returns a value. A method is the name given to functions and/or subroutines in certain programming languages.

A module consists of a single block of code that can be invoked in the way that procedure, function or method is invoked.

Finally, there are two methods to use, depending on if the given quadratic equation can be factored or not. 1.- The first one is the new Diagonal Sum Method, recently presented in book titled: "New methods for solving quadratic equations" (Trafford 2009). This method directly gives the two roots in the form of two fractions, without having to factor it. The innovative concept of this new method is finding 2 fractions knowing their product (c/a) and their sum (-b/a). This new method is applicable to any quadratic equation that can be factored. It can replace the existing trial-and-error factoring method since this last one contains too many more permutations. In general, it is hard to tell in advance if a given quadratic equation can be factored. However, if the new method fails to get the answers, then you can positively conclude that this equation can not be factored. Consequently, the quadratic formula must be used in solving. We advise students to always try to solve the given equation by the new method first. If the student gets conversant with this method, it usually take less than 2 trials to get answers. 2. the second one uses the quadratic formula that students can find in any algebra book. This formula must be used for all quadratic equations that can not be factored.

You can solve lineaar quadratic systems by either the elimination or the substitution methods. You can also solve them using the comparison method. Which method works best depends on which method the person solving them is comfortable with.

Experiments are a method for finding solutions to problems.

functions have independent existence means they are defined outside of the class e.g. in c main() is a function while methods do not have independent existence they are always defined inside class e.g. main() in Java is called method. ######## I've been studying OOP lately and had this question myself, so I will share my thoughts; I was taught that "A Function should do 1(one) thing and do it well." In specific Regards to PHP; The difference between a Method and a Function is that a Method is tied to a specific class. Hope this helps. -------------------------------------------------------------------------------------------------------- function can return value where as method can't that is the main difference between function and method --------------------------------------------------------------------------------------------------- Actually you are describing the difference between a function and a procedure. Function returns a value, procedure does not unless you are using c#, then everything is a function. In c# a function, to paraphrase the first answer, does and thing and does it well. A method contains functions. The most important method is the Main method. All functionality of a program must be referenced in the Main method because when you run a program, it starts at the beginning of the Main method, and stops wehn it hits end of the Main method.

using the quadratic formula or the graphics calculator. Yes, you can do it another way, by using a new method, called Diagonal Sum Method, that can quickly and directly give the 2 roots, without having to factor the equation. This method is fast, convenient and is applicable to any quadratic equation in standard form ax^2 +bx + c = 0, whenever it can be factored. It requires fewer permutations than the factoring method does, especially when the constants a, b, and c are large numbers. If this method fails to get answer, then consequently, the quadratic formula must be used to solve the given equation. It is a trial-and-error method, same as the factoring method, that usually takes fewer than 3 trials to solve any quadratic equation. See book titled:" New methods for solving quadratic equations and inequalities" (Trafford Publishing 2009)

sorry but are gone mad

at first the first person to solve the quadratic equation is from the middle kingdom of Egypt. Greeks were also able to solve the quadratic equation but that was on the unproper way. Greeks were able to solve the quadratic equation by geometric method or equlid's method. equlid's method contains only three quadratic equation. dipohantus have also solved the quadratic equations but he have solved by giving only two roots any they both were only of positive signs.After that arbhatya also gave the two formulas for quadratic equation but the bentaguptahave only accepted only one of them after theat some of the Indian mathematican have also solved the quadratic equation who gave the proper definations and formula and in this way quadratic equation have been formed.

process, method, protocol are synonyms of procedure

Comparing C# to other computer languages,A method with void, may be considered as a procedure, a function (returns nothing), or a subroutine.A method with a returning data type, is a function.If you don't have a other computer language background, a method in C# may be considered as a sequence of instructions to computer to be carried out.

The quadratic formula can be derived by used a method called completing the square. It's like using algebra to solve for x. The process is explained the related link "Derivation of Quadratic Formula".

It means you are required to "solve" a quadratic equation by factorising the quadratic equation into two binomial expressions. Solving means to find the value(s) of the variable for which the expression equals zero.
