Okay, here we're using the first rule of integration, which is if i integrate a x to the n dx, where a and n are numbers, what we get is a x to the n plus one over n plus one and plus c, if there are no limits.

So that, memorize, and over here then what we get is minus x cubed over three, just add one to the power, plus four x squared over two, power one here, so add one, i get two, and then five x, because here is being five x power zero, add one to zero, i get one, divide by one, i get still five square brackets because there are limits, and then three and minus two.

So what we have then is minus x cubed three plus two x squared minus five x, three and negative two...
