The Quadratic Equation, Formula, & Discriminant
If ax² + bx + c = 0 then x = .
The first equation is called the general form of a quadratic equation. The second equation is called the Quadratic Formula because it states the solution -- provides a formula for computing the simplified answer(s) by using the values of the first equation.
Restated: If an equation can be rearranged to look like ax² + bx + c = 0 then at most two answers answers may be found by using these formulas:
x = and x = .
