Question

Factorize : x3
+ x2
- 4x -4.

Answer 1

X3+X2-4X-4....
....
..
x^3 - 4x - x^2 + 4

f(x) = x(x^2 - 4) - (x^2 - 4)
........... = (x^2 - 4)(x - 1)
........... = (x - 2)(x + 2)( x - 1)

Answer 2

Hey There,
Here we are given a polynomial, which can be easily factorized as follows:


$x^3+x^2-4x-4 \\ \\ = x^2(x+1) - 4(x+1) \\ \\ =(x+1)(x^2-4) \\ \\ =(x+1)(x+2)(x-2)$


Hope this helps
