WEBGoogle Classroom. About. Transcript. The quadratic formula helps us solve any quadratic equation. First, we bring the equation to the form ax²+bx+c=0, where a, b, and c are coefficients. Then, we plug these coefficients in the formula: (-b±√ (b²-4ac))/ (2a) . See examples of using the formula to solve a variety of equations. Created by Sal Khan. copy paste
