Question

If f(x) = 4x² - x - 3, then what is the remainder when f(x) is divided by
x - 3?

Answer 1

30

Explanation:

Solve for f by simplifying both sides of the equation, then isolating the variable. It is pretty much like what we do with the normal equation.

Answer 2

remainder = 30

Explanation:

given f(x) divided by (x - h) then the remainder is f(h)

f(x) is divided by (x - 3) then remainder is f(3)

f(3) = 4(3)² - 3 - 3 = 4(9) - 6 = 36 - 6 = 30
