Solve an equation of the form a x 2 b x c 0 by using the quadratic formula. When a ne 0 there are two solutions to ax2 bx c 0 and they are x frac-b pm sqrtb2-4ac2a The formula can be used to solve any quadratic equation. Just enter the values of a b and c below.
I found them of use in College Algebra.
When a ne 0 there are two solutions to ax2 bx c 0 and they are x frac-b pm sqrtb2-4ac2a The formula can be used to solve any quadratic equation. X b b 2 4 a c 2 a. Step 1 If the coefficient of x 2 is not 1. 3x2-2x-10 After you click the example change the Method to Solve By Completing the Square Take the Square Root.
