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?
 
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".
