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

-8x^2 + 6x - 14

Explanation:

(3x^2 + 4x - 5) - (7x^2 + x + 9) = -4x^2 + 3x - 14

(-4x^2 + 3x - 14) - (4x^2 - 3x) = -8x^2 + 6x - 14

Answer 2

the difference is 14

Explanation:

Hello

I think I can help you with this

step 1

Subtracting 3x2 + 4x – 5 from 7x2 + x + 9

`7x^(2) +x+9-(3x^(2) +4x-5)\\=7x^(2) +x+9-3x^(2) -4x+5\\=4x^(2) -3x+14\\`

Step2

After subtracting 4x2 – 3x from this polynomial

`4x^(2) -3x+14-(4x^(2) -3x)\\4x^(2) -3x+14-4x^(2) +3x\\14`

the difference is 14

Have a fantastic day,I hope it helps
