 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.
