Which expression is equal to f(x) times g(x)?

Option (C)

Step-by-step explanation:

Given : f(x) =

           g(x) = x³ - 12

f(x).g(x) = f(x) × g(x)

            =

            =

            = (x + 6)(x³ - 12)

            = x(x³ - 12) + 6(x³ - 12)  [Distributive property]

            = x⁴ - 12x + 6x³ - 72

            = x⁴ + 6x³ - 12x - 72

Therefore, option (C) will be the answer.

step-by-step explanation:

what grade level is this? need to know so i can look in my old textbooks!

answer:   x = 3 + √11     and     x = 3 - √11

step-by-step explanation:

x² - 6x + 9 = 11

(x - 3)² = 11

x - 3 = ±√11

    x = 3 ± √11

x = 3 + √11     and     x = 3 - √11
