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 :)
