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

Answer:

-8x^2 + 6x - 14

Step-by-step 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

Answer:

the difference is 14

Step-by-step 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
