Type the correct answer in the box. use numerals instead of words. if necessary, use / for the fraction bar. subtracting 3x2 + 4x – 5 from 7x2 + x + 9 results in a polynomial. after subtracting 4x2 – 3x from this polynomial, the difference is

Step-by-step explanation:

7x^2 + x + 9 - (3x^2 + 4x- 5) =

7x^2 + x + 9 - 3x^2 - 4x + 5 =

4x^2 - 3x + 14

4x^2 - 3x + 14 - (4x^2 - 3x) =

4x^2 - 3x + 14 - 4x^2 + 3x =

14 < ur answer

14

Step-by-step explanation:

To subtract 3x2 + 4x – 5 from 7x2 + x + 9, we will take the difference of the two polynomials to have;

7x2 + x + 9 -(3x2 + 4x – 5)

= 7x²+x+9-3x²-4x+5

= 7x²-3x²+x-4x+9+5

= 4x²-3x+14

Further subtracting 4x²-3x from the resulting polynomial will give us;

4x²-3x+14 - (4x²-3x)

= 4x²-3x+14-4x²+3x

= 4x²-4x²-3x+3x+14

= 14

Therefore the final answer is 14
