How would you find the term x^2*y*z^5 in the expansion of (x-2y+z)^8? First you have to expand ((x-2y)+z)^8. I understand how to find the coefficient but I don't really understand how to find the term.

Try to do it in two steps: as , we get: So you must choose k = 3 above to get : , and now you must choose the correct power in to finally get Tonio
What do you mean with choose the correct power?
