ANS = x⁵-4x-4

if helpful mark me as the brainliest answer

Answer 2

Answer:

(x + 1)(x – 2) (x + 2)

Step-by-step explanation:

x3 + x2 – 4x – 4

Let x + 1 = 0

∴ x = -1

On substituting value of x in the expression

∵ f(-1) = (-1)3 + (-1)2 – 4(- 1) – 4 = 0

Clearly x + 1 is a factor of

f(x) = x3 + x2 – 4x – 4

∴ f(x) = (x + 1)(x2 – 4) (By actual division)

= (x + 1) (x – 2) (x + 2)

Hope it helps u☺
