Best ResponseYou've already chosen the best response.0uh huh i got =((a+3)+1)(1(a+3)^2) dont know what to do after that

Best ResponseYou've already chosen the best response.0\[f(a+3) = (a+3+1)(1(a+3)^2)\] just like pjschlotter said.

Best ResponseYou've already chosen the best response.0Solve it like: (a+3+1) = (a+4) (a+4) (1(a^2 +6a + 9)) (a+4) (a^2 6a 8)

Best ResponseYou've already chosen the best response.0You can also multiply (a+4) for the rest, but I don't think it's necessary... this form is clearer.

Best ResponseYou've already chosen the best response.0It's from the development of (a+3)^2, right? (b+c)^2 = b^2 + 2.b.c + c^2 So, (a+3)^2 = a^2 + 2.a.3 + 3^2 = a^2 + 6a + 3^2

Best ResponseYou've already chosen the best response.0ok kinda got it so if the number is 6 instead of 3 then it would be 12a instead of 6a correct?

Best ResponseYou've already chosen the best response.0It's (a+4) (a^2 6a 8), as I said!
