Best ResponseYou've already chosen the best response.0However there is a negative sign in fron of x so you have to multiply the first term with negative one.

Best ResponseYou've already chosen the best response.0I know how to do foil and all the math yet are you solving for x or leaving it as a quadratic?

Best ResponseYou've already chosen the best response.1Nothing nowhere says to solve for x. In fact, when I posted the hint I gave you. I left a comment below saying to "simplify the expression". How did you interpret "solve for x" from that?

Best ResponseYou've already chosen the best response.0x becomes a, so x is out of the picture. if your asked to simplify the expression then I guess all you have to do is the equation hero did setup for you.

Best ResponseYou've already chosen the best response.0Well I meant "a" and my problem was that I thought I was solving for "a".
