Question

What is the quadratic formula

Answer 1

a quadratic equation is any equation that can be rearranged in standard form as where x represents an unknown, and a, b, and c represent known numbers, where a ≠ 0. If a = 0, then the equation is linear, not quadratic, as there is no term.

Answer 2

${\sf{ x = {\dfrac{-b ± {\sqrt{b²-4ac}}}{2a}}}}$
