Question

If f(x) = 6x2 - 4 and g(x) = 2x + 2, find (f - g)(x).

Answer 1

6x^2-2x-6 is the correct answer

Answer 2

Answer:

6x² - 2x - 6

Step-by-step explanation:

note (f - g)(x) = f(x) - g(x), thus

f(x) - g(x)

= 6x² - 4 - (2x + 2) ← distribute

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

= 6x² - 2x - 6
