Answer:
The simplified expression is 3x²-12x+y ....
Explanation:
The given expression is:
3x²-14x+2x+7y-6y
Now solve for the variable x
Variable x has two terms:
-14x+2x = -12x
Thus the expression becomes:
3x²-12x+7y-6y
Now solve for the variable of y.
Variable y has two terms:
7y-6y= y
Thus the expression becomes:
3x²-12x+y
Thus the simplified expression is 3x²-12x+y ....
