Hi, I literally just registered so I have no idea about forum rules, also I'm not good in english.
1. Homework Statement
The equation is (x + 1)^2 dx.
U = (x+1)
DU = 1DX
Here I get (U^3) over 3 times DX = (x^3 + 3x^2 + 3x + 1) over 3 times 1
I simplify to (x^3) over 3 + x^2 + x +1 + C
The answer shows the same as my attempt but without the + 1 at the end. What happened to + 1 ?
