Question

If A = 3x
2 – 4x + 1, B = 5x
2 + 3x – 8 and C = 4x
2 – 7x + 3, then solve (A + B) – C

Answer 1

I am thinking it to be 4x .
I am not sure about the answer.

Answer 2

The value of (A+B)-C is "4x²+6x-10".

Step-by-step explanation:

$The \ given \ values \ are:\\A=3x^2-4x+1\\B=5x^2+3x-8\\C=4x^2-7x+3\\(A+B)-C=?\\So,\\(A+B)=(3x^2-4x+1)+(5x^2+3x-8)\\(A+B)=8x^2-x-7\\(A+B)-C=(8x^2-x-7)-(4x^2-7x+3)\\(A+B)-C=8x^2-x-7-4x^2+7x-3\\(A+B)-C=4x^2+6x-10$
