Jika dik f(x)= x+1 per x-1 dan g(x)=x ler x-2 Tentukan (f-g) (x) tlong segera d jwab ya...

[tex](f - g)(x) = f(x) - g(x) \\ \\ \frac{x + 1}{x - 1} - \frac{x}{x - 2} \\ \frac{((x - 2) \times (x + 1)) - x(x - 1)}{(x - 1)(x - 2)} \\ \frac{ {x}^{2} + x - 2x - 2 - {x}^{2} + x}{ {x}^{2} - 2x - x + 2} \\ \frac{ - 2}{ {x}^{2} - 3x + 2 } \\ - \frac{2 }{ {x}^{2} - 3x + 2 } [/tex]
