What is the quadratic formula?

Answer 1

x = [−b ± √(b2 − 4ac)]/2a

A, B, and C can all correspond to the original quadratic equation as follows: ax2 + bx + c = 0

The quadratic formula can only be used if the quadratic equation is equal to zero.
If [ Ax2 + Bx + C = 0 ], then

x = [ -B +/- sqrt( B2 - 4AC ) ]/ 2A

Answer 2

The roots of a quadratic equation in the form ax^2 + bx + c = 0 are

[-b +/- sqrt(b^2 - 4ac)]/(2*a)

Answer 3

If ax2 + bx + c = then

x = [-b +/- sqrt(b2 - 4ac)]/(2a)
