Could you please remind me of the quadratic formula?

anonymous · Answer

In basic algebra, the quadratic formula is the solution of the quadratic equation. There are other ways to solve the quadratic equation instead of using the quadratic formula, such as factoring, completing the square, or graphing. However, using the quadratic formula is often the most convenient way.

The quadratic equation is$$ax ^{2}+bx+c=0$$
