Question

express the product of (1/2y^2 - 1/3y) and (12y + 3/5) as a trinomial

Answer 1

you can use the FOIL method to solve this problem. if you aren't familiar with the FOIL method, the arrows indicate what you're multiplying. so after multiplying you should get \[(12/2)y^3 + (3/10)y^2 - 4y^2 - (1/5)y\] now you can simplify that and your answer will be \[6y^3 - (37/10)y^2 - (1/5)y\]
