expand (2+x)^5 up to x^2 term, hence, expand (2 + x + x^2)^5 up to the x^2 term.

I could do the first part, and the answer would be (32 + 80x + ...)

But how should i make use of the answer i got in the second part?

please help!

- binomial theorem! -

((2+x) + x^2)^5

you get the x^2 term really fast.
