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.

There are two methods of intersection?
The two methods of intersection typically refer to geometric and algebraic approaches. The geometric method involves graphing the equations and visually identifying the points where they intersect. The algebraic method involves solving the equations simultaneously, either by substitution or elimination, to find the exact coordinates of the intersection points. Each method has its advantages depending on the context and complexity of the equations involved.
What did diophantus discover?
Diophantus, often referred to as the "father of algebra," made significant contributions to mathematics, particularly in the field of algebraic equations. He is best known for his work "Arithmetica," which introduced methods for solving linear and quadratic equations and laid the groundwork for later developments in number theory. Diophantus also explored the concept of Diophantine equations, which are polynomial equations that seek integer solutions. His work influenced later mathematicians and the development of algebra as a discipline.
Can all quadratics be solved by completing the square?
Completing the square is one method for solving a quadratic equation. A quadratic equation can also be solved by factoring, using the square roots or quadratic formula. Solving quadratic equations by completing the square will always work when solving quadratic equations-You can also use division or even simply take a GCF, set the quantities( ) equal to zero, and subtract or add to solve for the variable
What is the third step in solving this equation by completing the square?
Completing the square is one method for solving a quadratic equation. A quadratic equation can also be solved by several methods including factoring, graphing, using the square roots or the quadratic formula. Completing the square will always work when solving quadratic equations and is a good tool to have. Solving a quadratic equation by completing the square is used in a lot of word problems.I want you to follow the related link that explains the concept of completing the square clearly and gives some examples. that video is from brightstorm.
