# Integration by substitution problem

1. The problem statement, all variables and given/known data

Using a suitable substitution find the solution to:

∫ (x+2)50(x+1)dx

2. Relevant equations

3. The attempt at a solution

I can't find a solution to this using substitution. Wolfram alpha give an answer that is too long to be calculated by hand. Can anyone work out the solution, or is there a mistake in the question which means it can't be solved?

$$Let\; u=x+2$$

What do you get if you let u= x+ 2? That seems to me to be the obvious substitution. It is certainly not "too long to be calculated by hand".
