You just have to factor all the denominators and have a look at it.

5x+5 = 5(x+1)

x^2 - 4 = (x+2)(x-2)

x-1 is done already

Looks to me like 5(x+1)(x-1)(x+2)(x-2) will cover it.

Note: Fix your notation. These two expressions are NOT the same.

2/5x+5

2/(5x+5)

You tell me how they are different and whether it matters.
