\[(x+2)^2(x1) + (x+2)(x1)^2\]multiply it out, step by step: \[(x+2)^2 = (x+2)(x+2) = x^2+2x+2x+4 = x^2+4x+4\] \[(x^2+2x+4)(x1) = x^3x^2+2x^22x+4x4 = x^3+x^2+2x4\] \[x^3+x^2+2x4 + (x+2)(x1)^2\]you do the rest, then simplify

@cwrw238 pretty sure that those 2s outside parentheses are supposed to be ^2

life would be easier if openstudiers couldn't copy and paste the questions, losing all of those valuable positional clues :)
