Question

From the sum of - 4x + 3x² +5 and -x + 2x-3, subtract 3x² - 8 + 9x.​

Answer 1

Answer:

Step-by-step explanation:

3x²-5x+2+(-5x²-8x+6)

3x²-5x+2-5x²-8x+6

3x²-5x²-5x-8x+2+6

-2x²-13x+8.

Now, we subtract the sum of -2x²-13x+8 and 4x²-9x+7,we get

-2x²-13x+8-(4x²-9x+7)

-2x²-13x+8-4x²+9x-7

-2x²-4x²-13x+9x+8-7

-6x²-4x+1.
