Question

What is the simplified expression for -3(2x- y) + 2y + 2(x+y)2

O 8x+y

o y-4x

0 7x-4x

0-4x-y

Answer 1

7y-4x.

Explanation:

I think that the last 2 shouldn't be there and the third option should be 7y-4x or all the options are incorrect.

-3(2x- y) + 2y + 2(x+y)

= -6x+3y + 2y+2x+2y

= -6x+2x+3y+2y+2y

= -4x+7y.
