Can someone show me how to do an indefinate integral?
I have to evaluate this problem.

First multiply the two terms. Then integrate the terms 3 x^3 and x^2 separately, and add the results.
Use the rule that the indefinite integral of a*x^n is [a/(n+1)]*x^(n+1),
where a is any constant.
The first term will be (3/4)*x^4. Now integrate x^2 for the other term. An arbitrary constant C can always be added, but is often omitted.
