Hello from MrBillDoesMath!

Answer:

None of the provided answers is correct.

Discussion:

The correct answer is "none of the provided answers".  The last term in 9x^2 - 2y + 3x^2 - 3y^2   is

-3y^2

None of the answers provided have a y^2 term!  Check it out. Someone made a bo-bo and it wasn't MrBill!

Thank you,

MrB
