Best ResponseYou've already chosen the best response.0you need to use the FOIL method (F) stands for First, (o) stands for Outer, (I) stands for inner and (L) stand for last. So therefore (2xa1)(x2) so F=2x.x O=2x.2 I=1.x L=1.2 So FOIL yeilds 2x^24x+X2 now simplify so we get 2x^23x2. This is a quadratic funtion that has the form ax+bx+c So a=2, b=3 and c=2 chow!
