Question 257289
Multiply and Divide Polynomials - including FOIL
I want to make sure that my answers are correct. Please let me know.
(ab)(ab)= my answer is A^2+ b^2 + ab + ba
With this one, I just want to make sure that ab & ba aren't able to be combined. I don't think so, but please let me know.
:
ab*ab = a^2b^2 and that's it, a big mistake on my part
:

:
(y-6)(y+3) = my answer is y^2 - 3y - 18
I'm pretty confident about this one.
:
This is right!

Last one:
Find the area of a rectangle

one side is 9x and the other side is 3x^2 + 2
so, a= l X w
27x^3 + 18x 
:
Right also!
