Question 121531
you started out great but messed up a little bit in your algebra, here is how it should be worked out. <br> 

{{{(3/(x^2+4x-5)) - ((2x)/(x-1))}}} ---> Factor the denominator
{{{(3/((x-1)(x+5))) - ((2x)/(x-1))}}} ---> Multiply to get common denominator
{{{(3 - (2x(x+5))) / ((x-1)(x+5))}}}  ---> Simplify
{{{(3 - 2x^2 -10x)/((x-1)(x+5))}}} ---> rewrite in proper form
{{{(-2x^2-10x+3)/((x-1)(x+5))}}} <br>

thats as simplified as it gets.
