where exactly?

I am trying to compute the following loop integral: $$ \require{cancel} \displaystyle \begin{align} I= \int \frac{d^4k}{(2\pi)^4}\bar u(p')\frac{[k^2k^\mu - (k\cdot p)\cancel{k}\gamma^\mu -(k\cdot p')\gamma^\mu\cancel{k}]}{[k^2-M^2+i\epsilon][(k-p)^2-m^2+i\epsilon][(k-p')^2-m^2+i\epsilon]}u(p)...
