Nobody's going to do your work for you. The guidlines of this forum state that you need to show some work before you get help.

This integral isn't tough, its just bloody long! For the inner integral:

$$\frac{a-b}{c}ln(\frac{b+c-cx_2}{b})-\frac{a}{c}x_2$$

Here, $$a=1-x_2$$

$$b=\lambda^2(1-x_2)$$$$c=q^2x_2-\lambda^2$$.

For the second integral, you're on your own mate... good luck.
