4/x+3-5/x-1 Tolong bantu saya

[tex] \frac{4}{x + 3} - \frac{5}{x - 1} \\ = \frac{4(x - 1) - 5(x + 3)}{(x + 3)(x - 1)} \\ = \frac{4x - 4 - 5x - 15}{x^{2} - x + 3x - 3 } \\ = \frac{ - x - 19}{x ^{2} + 2x - 3 } [/tex]
Maaf Kalau Salah

4/x+3 - 5/x-1
4(x-1) - 5(x+3) / (x+3) × (x-1)
4x-4 - 5x-15 / x²-x + 3x-3
-x-19 / x²+2x-3
