Penyelesaian pertidaksamaan 2x^-x-3 / x^-x-6 <0

2x² - x - 3
--------------- < 0
x² - x - 6

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

buat garis bilangan di
2x - 3 = 0
2x = 3
x = 3/2 = 1½
x = -1
x = 3
x = -2
+ + + - - - - - + + + + - - - - - + + +
------•--------•---------•--------•-------
``````-2 `````` -1 ````````` 1½ `````` 3
hp nya yg negatif
-2 < x < -1 atau 1½ < x < 3
