# Partial fraction question (maybe) watch

1. The question says:

1+x/1-2x is approximately equal to 1+ax+bx^2. Find values of a and b.

We only just started partial fractions today so I am assuming you have to use partial fractions to solve it, could anyone give me a hint to set me off?

Is that

If so this is a binomial expansion question

Is that or ?

Either way I'd be looking at the expansion of
