Is the product of - 5 + XNX + 4 equal to the product of 5 + X and X - 4

No

Step-by-step explanation:

(-5 + x) (x + 4) = - 5 * (x+4) + x * (x + 4)

= - 5x - 20 + x² + 4x

= - 5x + 4x + x² - 20 = - x + x² - 20

= x² - x - 20

(5 + x) (x - 4) = 5 * (x-4) + x (x-4)

= 5x - 20 + x² - 4x

= 5x - 4x + x² - 20 = x + x² - 20

= x² + x - 20
