∫3xdx/√(1-2x)

2. Relevant equations

3. The attempt at a solution

so i tried making u=3x which makes du=3dx but that substitution doesn't get rid of the x unde the square root. i tried u=1-2x and that gives du=-2dx and that doesn't get rid of the x on top. So i'm stuck and have no idea what to do here. Please help me out. Thanks!
