Use BODMAS, expand the brackets first.
So, is this the exact way the problem is:
If so, then above then can be re-written this way:Code:1 3x 1 ~~~~~~ - ~~~~~~~~~ + ~ 2x + 8 (x + 4)^2 2
Do you follow that?Code:1 3x 1 ~~~~~~~~ - ~~~~~~~~~~~~~~ + ~ 2(x + 4) (x + 4)(x + 4) 2
I suggest you google "simplifying" as next step: you'll get plenty of helpful sites
with the process fully explained; come back if you have more questions.
