Tea Lady Hi Fiona,

(1+3x)^-2 is the same thing as 1/(1+3x)^2

so all you need to do is to multiply your first 3 terms by x+4 and then tidy it up.

do i have to expand the top one using binomial expansion then multiply it by the answers i got for the bottom part or do i sub what i got for the bottom part as the x value in the top part??
