ANSWER

The complete factorization is


2 {x}^(2) - x - 6 = (2x + 3)(x - 2)

EXPLANATION

The given expression is


2 {x}^(2) - x - 6

This is a quadratic trinomial with,


a=2,b=-1,c=-6


ac = - 12


Two factors of -12 that adds up to -1 are


- 4,3


We split the middle term to obtain,



2 {x}^(2) - 4x + 3x- 6

We factor to get,


2x(x - 2) + 3(x - 2)


We factor further to get,



\therefore2 {x}^(2) - x - 6 = (2x + 3)(x - 2)
