Question

Which model shows the correct factorization of x2-x-2

Answer 1

The answer is (x-2)(x+1).

Explanation:

You have to elaborate the expression :

`{x}^(2) - x - 2`

`{x}^(2) + x - 2x - 2`

Next you can take out the common terms(factorize) :

`{x}^(2) + x - 2x - 2`

`x(x + 1) - 2(x + 1)`

`(x - 2)(x + 1)`

Answer 2

its b
