Which expression is equivalent to (x2+3x−5)− (4x2+3x−6) PLEASE HURRY>>>>
A. 5x2+6x−11

B. −3x2+1

C. −3x2+1

D. −3x4+6x2+1

B

Step-by-step explanation:

Given

x² + 3x - 5 - (4x² + 3x - 6) ← distribute parenthesis by - 1

= x² + 3x - 5 - 4x² - 3x + 6 ← collect like terms

= - 3x² + 1 → B

step-by-step explanation:

for exempl this   system of equations   y = x - 3

                                                                y = 2x - 5

look   the line : y = x -3     ( red)

                            the line : y = 2x -5 ( bleus)
