Can someone post some relatively simple binomial expansion questions with answers?

Examples:

(x+2)^2 = x^2 + 4x + 4

(2x-5y)^7 = 128x^7 + -2240x^6y + 16800x^5y^2 + -70000x^4y^3 + 175000x^3y^4 + -262500x^2y^5 + 218750xy^6 + -78125y^7
Make up some questions yourself and use Maxima to find the answers. =)
