#(x-3)/10-11/(10(x-3)#

Explanation:

Use long division.

#(x^2-6x-2)/(10x-30)=x/10-(3x+2)/(10x-30)#

Then, divide #(3x+2)/(10x-30)#

#(3x+2)/(10x-30)=-3/10-11/(10x-30)#

Now, put that back into the original expression to get

#(x^2-6x-2)/(10x-30)=x/10-3/10-11/(10x-30)#

Simplify to get

#(x^2-6x-2)/(10x-30)=(x-3)/10-11/(10(x-3)#
