Tolong Bantu ya buat besok No.12

2/x+2 - 3/x+3=2(x+3)-3(x+2)/ (x+2)(x+3)
= 2x+6-3x-6 / x²+5x+6
= -x/ x²+5x+6

[tex] \frac{2}{x + 2} - \frac{3}{x + 3} \\ = \frac{2(x + 3) - 3(x + 2)}{(x + 2)(x + 3)} \\ = \frac{2x + 6 - 3x - 6}{(x + 2)(x + 3)} \\ = \frac{2x - 3x + 6 - 6}{(x + 2)(x + 3)} \\ = \frac{ - x}{(x + 2)(x + 3)} [/tex]
Jawaban : D

Maaf Kalau Salah
