Simplify the following expression : 2x − 8y 3x^2 7y − 12x. 3x^2 − 14x − y 3x^2 − 10x − y 3x^2 − 10x − 15y 3x^2 10x − y

If you would like to simplify the expression 2x - 8y + 3x^2 + 7y - 12x, you can do this using the following steps:

2x - 8y + 3x^2 + 7y - 12x = 3x^2 + 2x - 12x - 8y + 7y = 3x^2 - 10x - y

The correct result would be 3x^2 - 10x - y.

First subtract 10 from both side
y^2+6y-16=0
(y+8)(y-2)=0
-8 and 2
