1. Make the substitution t = (u-3)^2 - 8

2. Try integration by parts, so that inside the integral sign, you differentiate ln(x) and integrate sqrt(x), the product of these two will be a power function.

3. Make the substitution s = u-3, multiply out the square, and then you will have a sum of power functions. - Sep 6th 2012, 07:20 PMProve ItRe: How to solve Integrals?
