which of the following terms appear in the expansion of (x+y)^8? the letter a in each term represents a real constant. A. ax^4 Bax^4y^4 C. ay^4 D. ax^3y^5

10a^3+277a^2-132a-792

step-by-step explanation:

(2a+11)(5a-12)(foil)

=10a^2-24a+55a-132 =10a^2+31a-132

(10a^2+31a-132)(a+6)

=10a^3+60a^2+31a^2+186a^2-132a-792 =10a^3+277a^2-132a-792
