Subtract 2 from both sides

6x²-x-2<2-2

Simplify

6x²-x-2<0

Find the signs of the factors of 6x²-x-2

Identify the intervals that satisfy the required condition: < 0

 

-1/2 < x < 2/3

 

 

Hope this helps. If not, sorry mate.

Elaborating on penquino

 

Its 6x^2 - x -2

 

So you factor it

 

(3x - 2)(2x + 1) < 0

 

So you have

 

2/3 and -1/2
