Ответ:
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
Ответ:
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.
