Use partial fractions:

Now use a linear u-substitution on the first fraction and the other two fractions are easy.

We havent got to partial fractions. Thats next section. We are supposed to solve it without partial fractions?

That's not really partial fractions though. You split a fraction into two partial fractions if the denominator has a higher order than the numerator.

What's happening here is you're just factoring out whole numbers and leaving a constant as the numerator of your fraction (thus making it integrable).


Why did the vector cross the road?
It wanted to be normal.
