Question

5/1+x - 3/1-x - 6/11-x^2 =0

Answer 1

5/1+x - 3/1-x - 6/11-x² =0

5(1-x) - 3(1+x) = 6
-----------------      -----
    (1-x)(1+x)        (11-x²)

5-5x-3-3x     6
------------ =  --------
1-x²               (11-x²)

2-8x        6
--------=   -----
1-x²         (11-x²)

2(1-4x)/1-x² = 6/(11-x²)
