Question

subtract the sum of 5x²-6x+4and -4x²-2x+3 from 0​

Answer 1

Step-by-step explanation:

Sum =

(5x²-6x+4) + (-4x²-2x+3)

= 5x² - 6x + 4 - 4x² - 2x + 3

= x² - 8x + 7

Subtract the sum from 0

0 - (x² - 8x + 7)

0 - x² + 8x - 7

-x² + 8x - 7

Answer 2

Answer:

5x²-6x+4 +(-4x²-2x+3)

= x²-8x+7

Now.

0-(x²-8x+7)

= -x² +8x-7
