Question: how to solve the quadratic equation by factorization method?
Answer: What we need to do is simply set each factor equal to zero, and solve each equation for x. The answers are x = − 7 x = - \,7 x=−7 and x = 2 x = 2 x=2. ...  The left side of the equation is a binomial. ...  Note, I can also factor out 2 x 2x 2x instead of −2x.
