For the first problem, this is how far I get:
But for the second, I don't know how to set it up.
Thank you for your help!
in the first integral you have two mistake the first one to decide A ,B ,C values cuz
B=-1/2 , A=-1/4 , C=1/4
this is the first one the second
the integrate of 1/x^2=-x^-1 not ln(x^2)
