subtracting 3x2 + 4x – 5 from 7x2 + x + 9 results in a polynomial. after subtracting 4x2 – 3x from this polynomial, the difference is

14

Step-by-step 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)
