Answer:14

Explanation:

Please be certain to use " ^ " to denote exponentiation:

3x^2 + 4x – 5, 7x^2 + x + 9, 4x^2 - 3x

First, perform this subtraction:

7x2 + x + 9

-(3x2 + 4x – 5)

-----------------------

4x^2 - 3x + 14

Next, subtract 4x^2 - 3x from the above result:

4x^2 - 3x + 14

-(4x^2 - 3x)

------------------------

14 (answer)
