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)
------------------------
