And now this is pretty straightforward to evaluate. This is going to be equal to the antiderivative of x to the third is x to the fourth over four. So this is going to be three times x to the fourth over four I could write it that way or let me just write it, x to the fourth over four and then the antiderivative of x squared is x to the third over three. So minus x to the third over three and this is an indefinite integral. There might be a constant there. So let me write that down and we're done. The big takeaway is you just have to do a little bit of distribution to get a form where it's easy to evaluate the antiderivative.
