Answer:

Explanation:

On each of those equations, combine like terms.


(3x^(2)-7x +14) + (5x^(2) +4x-6)\\ 3x^(2) +5x^(2) = 8x^(2) \\-7x+4x=-3x\\14-6=8\\Your expression would be: 8x^(2) -3x+8

This expression would be equivalent to B


( 2x^(2) -5x-3)+(-10x^(2) +2x+7)\\2x^(2) -10x^(2) =-8x^(2) \\-5x+2x=-3x\\-3+7=4\\

Your expression would be:
-8x^(2) -3x+4

This expression would be equivalent to A


( 12x^(2) -2x-13) + (-4x^(2) +5x+9)\\12x^(2) -4x^(2) =8x^(2) \\-2x+5x=3x\\-13+9=-4

Your expression would be:
8x^(2) +3x-4

This expression would be equivalent to C
