Quadratic equations have symmetry, the left and right are like mirror images:The midline is at −b/2, and we can calculate the value w with these steps:First, "a" must be 1, if not then divide b and c by a: b = b/a, c = c/a mid = −b/2 w =√(mid2 − c) ...
Solving Quadratics with a Leading Coefficient of 1 In the quadratic equation x2+x−6=0x2+x−6=0, the leading coefficient, or the coefficient of x2x2, is 1. We have one method of factoring quadratic equations in this form. How To: Given a quadratic equation with the leading coeffic...
