Question

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

Answer 1

7x^2 + x + 9 - [3x^2 +4x -5] = 4x^2 -3x +14

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

The difference is 14

Answer 2

Answer:

the difference is 14

Step-by-step explanation:

subtracting 3x2 4x – 5 from 7x2 x 9 results in a polynomial

Subtract $3x^2+4x-5 from 7x^2+x+9$

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

Multiply negative inside the parenthesis

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

$4x^2-3x+14$

Now we subtract 4x^2 -3x from the result $4x^2-3x+14$

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

$4x^2-3x+14-4x^2+3x)$

14
