What is this formula?

• This is the completing the square method.

• This is the quadratic formula.

• This is the zero product property.

• This the discriminant.

Answer explanation

The quadratic formula, given by x = (-b ± √(b²-4ac)) / 2a, is used to find the roots of a quadratic equation. It is distinct from completing the square, the zero product property, and the discriminant.
