Question 945655
That complex fraction as pure text:


(2/(x-1))/(1/x-3/(x-1))


Placing inside the triple braces rendering tags for the system,
{{{(2/(x-1))/(1/x-3/(x-1))}}}


The lowest common denominator is {{{x(x-1)}}}.
Begin by multiplying the entire complex fraction by {{{(x(x-1))/(x(x-1))}}}, and continue simplification from that.


Finished result is  {{{-(2/(2x^2-x))}}}
