1. Do a long division. 2. Apply:
Thank you Is the correct way to continue by let u=x^2-4x+5 du=(2x-4)dx so (x-2)dx=du/4 After this I am not quite sure what to do
Can you continue now?

For the second term: you should be able to finish it off now..
Thank you I have worked the answer out to be 2ln(x^2-4x+5) +3tan^-1(x-2) + x+C ??
