Explanation:
You are able to bounce answers and ideas off each other and learn things you didn't know. You are able to take more notes.
I think I can help, but only with the first two sections (sorry!).
A: (11z^2-4z+2)+(12z^2-2z+3)+(13z^2-3z+3)
(11z^2+12z^2+13z^2)+(-4z+-2z+-3z)+(2+3+3)
A: 36z^2-9z+8
B: (5z^3+40z^2+7z-15)-(36z^2-9z+8)
5z^3+(40z^2-36z^2)+(7z+9z)+(-15-8)
B: 5z^3+4z^2+16z-23
