Quadratic equation with given roots
Webx = (-B +- sqrt (B^2 + 4AC))/2A (remember, minus -C^2 is the same as plus C^2) Compare this to the solution of our original equation: x = (-B +- sqrt (B^2 - 4AC))/2A. As long as A, B, and … WebThe 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. Sort by: Top Voted Questions
