Question

2a/a+1-2a/a-1+a+3/a sqaure-1​

Answer 1

Answer:

Step-by-step explanation:

$\frac{2a}{a + 1} - \frac{2a}{a - 1} + \frac{a + 3}{a^{2} - 1}$

$\frac{2a}{a + 1} - \frac{2a}{a - 1} + \frac{a + 3}{(a - 1)(a + 1)}$

$\frac{2a^{2} - 2a - 2a^{2} - 2a + a + 3 }{(a +1)(a - 1)}$

$\frac{3 - 3a}{(a + 1)(a - 1)}$

$\frac{-3(a - 1)}{(a - 1)(a + 1)}$

$\frac{-3}{a + 1}$
