This formula is called the quadratic formula.
The quadratic formula is derived by completing the square. That is as much as I can tell you.
In general, quadratic equations have graphs that are parabolas. The quadratic formula tells us how to find the roots of a quadratic equations. If those roots are real, they are the x intercepts of the parabola.
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".
A quadratic equation.
The discriminant, because it helps you to discriminate between the type (and number) of roots.
The quadratic formula is used to solve the quadratic equation. Many equations in which the variable is squared can be written as a quadratic equation, and then solved with the quadratic formula.
aryabhatt's quadratic formula
There are an infinite number of different quadratic equations. The quadratic formula is a single formula that can be used to find the pair of solutions to every quadratic equation.
This formula is called the quadratic formula.
you use the quadratic formula in math when the quadratic equation you are solving cannot be factored.
8th grade upto college will study the quadratic Formula. ~ I'm in the 6th grade and I study the quadratic formula...
Yes.

The discriminant of the given quadratic expression is -7
Well, if the given quadratic equation cannot be factored, nor completed by the square, try using the quadratic formula.
