Select one of the factors of 3x2 + 4x - 4.

(x + 4)

(3x + 2)

(3x - 2)

(x - 2)

X-c where c is a number is a factor of the function if and only if the result of the operation gives a remainder is 0. It has been said that R is equal to the function of c. Calculation for this are as follows;

R = f (c) = 0 = 3x^2 + 4x - 4

Solving for x, we obtain

x = 2/3

x = - 2

From the choices the answer is the 3rd option.
