Question 374184: I am stuck on part of my Algebra homework. I have tried changing the signs around, foil, and everything else I can think of. It is driving me crazy. Here is what I have got so far.

The question is:
Find binomials that fit the conditions below
a) Write two binomials whose product is a binomial.
(a-b)(a+b)=a^2-b^2
b) Write two binomials whose product is a trinomial.
(x+1)(x+2)=x^2+3x+2
c) Write two binomials whose produce is a 4-nomial.
(x+y)(a+b)=(x+y)a+(x+y)b=ax+ay+bx+y
d) Write two binomials whose product is a 5-nomial.

Every combination I try, I either end up with a 4-nomial or a 6 or more-nomial. I am pretty positive I have a-c right but d is stumping me and could really use some guidance.
