    umm, no.. But we are supposed to use the Binomial theorem, and it makes me feel like i'm looking at a foreign language..

    (x+y)^5=x^5+5x^4y+10x^3y^2+10x^2y^3+5xy^4+y^5 and replace y with -10

    its probably because they don't have time to go over everything and they just mainly want to see if you can multiply
