Tolong di Jawab no 3 nya aja, pake cara y

[tex] \frac{3}{x + 1} + \frac{3}{x - 1} \\ = \frac{3}{(x + 1)( x- 1)} + \frac{3}{(x + 1)(x - 1)} \\ = \frac{3(x - 1)}{(x + 1)( x - 1) } + \frac{3(x + 1)}{(x + 1)(x - 1) } \\ = \frac{3x - 3}{(x + 1)(x - 1)} + \frac{3x + 3}{(x + 1)(x - 1)} \\ = \frac{6x}{(x + 1)(x - 1)} [/tex]

smoga membantu:)
