Answer:
-2x²-8x+12
Step-by-step explanation:
(f-g)(x)
--> f(x) - g(x)
--> 3x² - 2x + 4 -(5x² + 6x - 8)
--> 3x² - 2x + 4 -5x² - 6x + 8
--> -2x²-8x+12
Answer:
-2x^2- 8x + 12.
Step-by-step explanation:
(f - g)(x) = f(x) - g(x)
= 3x^2 - 2x + 4 - (5x^2 + 6x - 8)
Distributing the negative over the parentheses:
= 3x^2 - 2x + 4 - 5x^2 - 6x + 8
= -2x^2- 8x + 12.
