bentuk sederhana dari 2/x+2 - 3/x+3

2/x+3-3/x+3 = 5/1 karna x+3 : x+3

[tex] \frac{2}{x + 2} - \frac{3}{ x + 3} \\ = \frac{2}{(x + 2)(x + 3)} - \frac{3}{(x + 2)(x + 3)} \\ = \frac{2(x + 3)}{(x + 2)(x + 3)} - \frac{3(x + 2)}{(x + 2)(x + 3)} \\ = \frac{2x + 6 - 3x + 6}{(x + 2)(x + 3)} \\ = \frac{ - x + 12}{(x + 2)(x + 3)} [/tex]
-x + 12
= ---------------
x² + 5x + 6

NB : (x+2)(x+3) itu dari KPK x+2 dan x+3
