Subtract the second expression from the first . (5x^2-3x+5) - (3x^2-4x-7) a. 2x^2+x+12 b. 2x^2-7x+12 c.8x^2+x+12 d.2x^2+x-2

(5x² - 3x + 5) - (3x² - 4x - 7)     Distribute/multiply - into (3x² - 4x - 7)

5x² - 3x + 5 - 3x² + 4x + 7    Combine like terms

2x² + x + 12

The answer is A

56

step-by-step explanation:

we can't see all full 4 options, but if this is the full option, than the very left one is correct:
