Simplify the following expression:
2x − 8y + 3x2 + 7y − 12x.

a. 3x2 − 14x − y
b. 3x2 − 10x − y
c. 3x2 − 10x − 15y
d. 3x2 + 10x − y

Hello,

The answer is C: 3x^2 - 10x - y.  

:)

B. 3x² − 10x − y

Step-by-step explanation:

To simplify this, we combine like terms:

2x - 8y + 3x² + 7y - 12x

2x has a like term with -12x; 2x-12x = -10x.  This gives us

-10x - 8y + 3x² + 7y

-8y has a like term with 7y; -8y+7y = -1y.  This gives us

-10x - 1y + 3x²

In order by power of x, we have

3x² - 10x - y
