Will mark ! what is the difference when 5x^2 − 3x + 2 is subtracted from 4x^2 − 7x + 9? a) x^2 − 4x + 7 b) −x^2 − 4x + 7 c) 9x^2 − 4x − 11 d) −9x^2 − 4x + 7

B

Step-by-step explanation:

4x² - 7x + 9 - (5x² - 3x + 2) ← distribute by - 1

= 4x² - 7x + 9 - 5x² + 3x - 2 ← collect like terms

= (4x² - 5x² ) + (- 7x + 3x ) + (9 - 2)

= - x² - 4x + 7 → B

not sure but it may be b, as i said i'm not sure.
