No explanation in textbook C4 partial fractions!

Hi,

I'm completely puzzled about how they turn proper and improper fractions into partial fractions in the textbook. I've got a bit of an idea for the proper fractions but i'm not completely sure.



Snap! I just did the second box backwards and figured out how they got it. But still how are you meant to know whether it splits into 2 or 3 parts or what values to split it into?

Thanks!

Ok i've figured out it's got something to do with the quadratic which forms in the numerator. Are you meant to multiply the numerator by the denominator?
Can you post an example of what you're on about...?
