Algebraic Formula Sheet

Quadratic Formula To solve ax2 + bx+ c= 0, a6= 0, use : x= 2b p b 4ac 2a. The Discriminant The discriminant is the part of the quadratic equation under the radical, b2 4ac. We use the discriminant to determine the number of real solutions of ax2 + bx+ c= 0 as such : 1. If b2 4ac>0, there are two real solutions. 2. If b2 4ac= 0, there is one ...
