Question

Integrate: dx/[(x+2)^(1/4) + 1]
Use the the following substitution on the above integral: x + 2 = u^4

Solve using partial fractions.

I tried this:
Using substitution provided, I get:
Integral of 4(u^3)du/(u+1)
then using partial fractions I would have the following equation:
4(u^3)/(u+1) = A/(u+1)
At this point, im pretty sure im wrong. Cause I think with my equation, A = 0.
