(6x-20)/(-x+4)

Question

Can this be simplified further 

Answer 1

(6x-20)/(-x+4)

2(3x-10)/(-x+4)

No

Answer 2

Depending on how you intend to use it, breaking out the -6 may be useful, as in:

 

(6x-20)/(-x+4) + 6 - 6 =

(6x-20 - 6x + 24)/(-x+4) - 6 =

4/(4-x) - 6

 

Then x only appears once.

Answer 3

Yes, but only slightly:  (6x-20) / (4-x)     One less sign!

 

If an horizontal division line is available, separating numerator from denominator, then all four parentheses marks can be deleted.
