If (2x^2-5x+7)-(4x^2+2x-11), what is the result?

download app named "PhotoMath" it gives u answer to every math problem.

- 2x² - 7x + 18

Step-by-step explanation:

Given

(2x² - 5x + 7) - (4x² + 2x - 11) ← distribute parenthesis

= 2x² - 5x + 7 - 4x² - 2x + 11 ← collect like terms

= - 2x² - 7x + 18

f(x) has value 150 at x= 0

and 0 at x= 3

so d(f(x))/dt = slope = -150/3 = -50

d i think
