"Evaluate the following indefinite integrals:
"S" (3x^2 2)/(x^3  2x + 1)^3 dx"
We're practicing the substitution rule, and I know how to do it, but I don't know what/how to substitute in this question.
btw: "S" is the integral sign.

substituition for the denominator
giving you du= 3x^22
leaving you with just 1/u^3 then find the anti derivative of that and youll have you answer. Don't forget your c
