Best ResponseYou've already chosen the best response.1okay, so first we should get everything on the same side so its =0. so to do that we would subtract 3x^2 to get 3x^221x15, now personally i dont like working with negatives so if you multiply it all by 1 you will get 0=3x^2+21x+15, does that make sense?
