I need to find the laplace transform of

$\displaystyle (1-\pi)u_\pi-(t-\pi)u_{2\pi}$

I can see how to find the first part of it with the formula

$\displaystyle L[u_c(t)f(t-c)]=e^{-cs}F(s)$

But the second part $\displaystyle (t-\pi)u_{2\pi}$ doesn't seem to work with that. How do I start to solve the second part?
