Question 325504
Simplify first,
{{{2/(x-1)-4/(x-1)=-2/(x-1)}}}
Next step, find a common denominator,
In this case,{{{(x-1)(x-2)}}}
{{{2/(x-1)-4/(x-1)+1/(x-2)=(-2(x-2))/((x-1)(x-2))+(x-1)/((x-1)(x-2))}}}
{{{2/(x-1)-4/(x-1)+1/(x-2)=(-2(x-2)+(x-1))/((x-1)(x-2))}}}
{{{2/(x-1)-4/(x-1)+1/(x-2)=(-2x+4+x-1)/((x-1)(x-2))}}}
{{{2/(x-1)-4/(x-1)+1/(x-2)=(-x+3)/((x-1)(x-2))}}}
{{{2/(x-1)-4/(x-1)+1/(x-2)=-(x-3)/((x-1)(x-2))}}}
