Question 72454
Determine the constant term in the expansion of (2x-2/5x^2)^8.

I am doing this math independently. I have looked through my
textbooks, but cannot find what a consant term is. I have 
expanded this by binomial expansion but there is not one constant 
term in the solution as all constants are differnt numbers with 
differnt x values. 

Thank you
Kristen

(2x-2/5x^2)^8

Did you mean

{{{(2x - 2/5x^2)^8}}}

or did you mean

{{{(2x - (2/5)x^2)^8}}}

Post again telling us which one you mean.
