I finally remembered how to work the second problem after about 30 minutes of beating my head
The first problem shows the answer to be this: (3q + 2) (3q^2 +5)
Yeah, it's the same thing as what I had, but you went an extra step.
I can't believe I actually remembered how to do...
Oh, and how I got that second one...
(p-7)(p+2)
would be... p^2-7p+2p-14 after multiplying it out, then simplify.
p^2-5p-14
Then you would multiply by the -1 to make it: -p^2+5p+14
(just in case they want you to show your work)
I haven't taken Algebra for several years, and I can't believe how much I've forgotten.
I think this is what he wants you to do.. if I remember correctly...
9q^3+6q^2+15q+10=
3q^2(3q+2)+5(3q+2)
And...
-p^2+5p+14=
(p-7)(p+2)
Edited: flip-flopped my signs in the second problem. Whoops!
