# Homework Help: How to find the integral of (3x^3 - 1)/x from 1 to e

### IntegrateMe

$$\int_{1}^{e} \frac{3x^3-1}{x} dx$$

What method? I haven't seen a problem like this before.

Re: Integration

Remember how (a+b)/c = a/c + b/c ? Use a similar principle.

Re: Integration

Ah, OK so:

$$\int_{1}^{e} 3x^2 -\frac{1}{x} dx$$

In which case this becomes a simple integration problem.

Thank you!
