Answer:

X - 2

Step-by-step explanation:

X³ - 2x - 4      = we can use 4th identity ( x + a)(x + b) = x2 + (a + b) x + ab)

   x + 2                x = x  , a = -2  , b = 2

So we can replace ( x + a)(x + b) as (x+-2)(x+2) = (x-2)(x+2)

so (x-2)(x+2)

        x + 2      (YOU CAN CANCEL UPPER AND LOWER X + 2) = X -2

SO ANSWER = X - 2

Hope it helps :)
