1. factor out a 2 and an "x" 
2. use your tools of algebra to solve for one of the x's
you have $2x(x-2)$
HINT: one of your x values is zero.

next time, @Brunette try to help them get the answer rather than just giving it to them. It helps them learn better.

first factor..... (2x-2)     (x+2)
                      -----
                         2    = (x -0)
zero out ......     x=0, x=-2
