Bab Pertidaksamaan
Matematika SMP Kelas IX

(x - 6) / (x - 3) >= (x - 2) / (x + 1)
((x - 6)/(x - 3)) - ((x - 2)/(x + 1)) >= 0
((x - 6) (x + 1) - (x - 2) (x - 3))/((x - 3)(x + 1)) >= 0
(x² - 5x - 6 - x² + 5x - 6)/((x - 3) (x + 1)) >= 0
(-12) . (x - 3) (x + 1) > 0
(-12) . (x - 3) (x + 1) < 0 → (karena (-12) < 0)

x + 1 > 0
x > -1
-1 < x

x - 3 < 0
x < 3

-1 < x < 3
