O A. 6x2 - 2x - 6
O B. 6x2 - 2x-2
O c. 44²-6
O D. 2x - 5x2 - 2

Respuesta :

Answer:

A

Step-by-step explanation:

Note that (f - g)(x) = f(x) - g(x)

f(x) - g(x)

= 6x² - 4 - (2x + 2) ← distribute parenthesis by - 1

= 6x² - 4 - 2x - 2 ← collect like terms

= 6x² - 2x - 6 → A

Answer:

A.  6x^2 - 2x - 6.

Step-by-step explanation:

( f - g)(x)

= 6x^2 - 4 - (2x + 2)

= 6x^2 - 4 - 2x - 2

= 6x^2 - 2x - 6.
