Answer 1

You need like denominators. The LCD= 2(x-6)(x+6)
(x-7)*(x+6).............6*(2)
------------------ + ------------
2(x-6)*(x + 6).....(x² - 36)*(2)

x² - x - 42 + 12
-------------------
2(x + 6)(x - 6)

x² - x - 30
-------------
2(x+6)(x-6)

(x-6)(x+5)
-------------
2(x+6)(x-6)

...x+5
---------
2x +12

Answer 2
