bantuin dong. materi pertidaksamaan rasional

x² - 4x + 3
-------------- ≥ 0
x² - 3x

(x - 3)(x - 1)
---------------- ≥ 0
x(x - 3)
buat garis bilangan di
x - 3 = 0
x = 3
x - 1 = 0
x = 1
x = 0
+ + + + - - - - - - + + + + + + +
---------•----------•----------•---------
`````````` 0 `````````` 1 ```````````` 3
x ≤ 0 atau x ≥ 1
syarat
x(x - 3) ≠ 0
x ≠ 3
x ≠ 0
maka hp
x < 0 atau 1 ≤ x < 3 atau x > 3
