Which is the simplified form of the following expression? 7x - 9y + 4x^2 - 2x + 12y


A. 13x + 3y

B. 11x + 21y

C. 4x2 + 5x + 3y

D. 4x2 + 9x + 21y

Answers

i think its c because 7x-2x is 5x, -9y + 12y is 3y, and 4x^2 stays the same

Rearrange it so the x is on the left and y is on the right starting with the highest x value which is x^2

4x^2 + 7x - 2x - 9y + 12y
= 4x^2 + 5x + 3y

There the answers is C.
