I have to evaluate the integral of (x-9)4^xdx

2. Relevant equations

Integration by parts

3. The attempt at a solution

I setted the (x-9) as D and the 4^x as I. The problem is that im not sure what the antiderivative of 4^x would be. Im guessing its mostly like 4^x+1 all over x+1. If this is true, then there is another problem. Im not sure of how i could integrate 4^x+1(x+1)^-1. Help is desperate at this moment, since i only have 6 hours to submit my homework. Please give me support. Thanks.
