33 - x(2 + 3x) > 0
33 -2x -3x² >0
-(3x² +2x -33) >0
3x²+2x -33 < 0
3x² +11x -9x -33< 0
x(3x +11) -3(3x +11) < 0
(x -3)(3x +11)< 0
-11/3 < x < 3
-3.667 < x < 3
- 3 ≤ x < 3
so, least value of x = -3
33 -2x -3x² >0
-(3x² +2x -33) >0
3x²+2x -33 < 0
3x² +11x -9x -33< 0
x(3x +11) -3(3x +11) < 0
(x -3)(3x +11)< 0
-11/3 < x < 3
-3.667 < x < 3
- 3 ≤ x < 3
so, least value of x = -3
