Best ResponseYou've already chosen the best response.0yeah, so take my answer and factor out (x3)^2. that leaves you 3(x+1) + (x3) in the parentheses, which is 3x+3+x3 = 4x. let me know if that doesn't make sense. :)

Best ResponseYou've already chosen the best response.0what i did was factor out (x3)^2 from that. both of your terms have (x3)^2 as a common factor.
