When dealing with partial fractions when do you have to divide is it when the denominator has a higher degree of power than the numerator.

Here's bi, I found it really difficult too when I first did it, it's just about rearranging and substitution really. There's probably and easier method but I Hope it helps :smile:

What I wrote on the mark scheme was what I put down in the paper so I'm hoping I got the majority right but probably missed some method marks - 71-72 maybe? :smile:

Core 4 will be hard :frown:
