Pls expand this for me
√ (4+∈²)
where ∈ is a variable (u can call it E if u like). I know its the binomial expansion but i can't seem to do it.

Re: Pls expand this for me
Why would you want to expand that? Is it not already in simplest form?

No, its not. We have to somehow expand that and compare it to another equation.

Re: Pls expand this for me
yes they are, the binomial expansion can only be used in the form
(1+a)^n where -1 < n < 1.
