binomial theorem again
posted by nicholas .
How do i do this question using the binomial theorem concept? It says,
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!

Please don't repeat questions.
