I need to do binomial expansion on this: (4-x) / √(1+2x) which I've written as (4-x).(1+2x)^½ How do i simplyfy it so I get it in the form (1+x)^n Am I being stupid or what!? Many thanks in advance

Many thanks in advance You could do this. Let so your expression is then use a binomial expansion for each separately then multiply by the fraction out front, then substract, then replace u with 2x.
