Section 3.2a - Solving Quadratic Equations by Factoring
... A quadratic equation – one that contains an x2 term – can be solved by setting the equation = 0, factoring, then setting EACH factor = 0, and solving the new equation(s). When factoring, remember to ask yourself: A. Can I take anything out? 1. 5x2 – 6x = 0 ...
