<br>
{{{4(2/x-5x^4/x^5+3)}}}<br>
{{{4(2/x-5/x+3)}}}  [simplify the middle term]<br>
{{{4(2/x-5/x+3x/x)}}}  [get a common denominator]<br>
{{{4(1/x)(2-5+3x)}}}  [factor out the common denominator factor]<br>
{{{(4/x)(3x-3)}}}  [simplify]<br>
{{{(4/x)(3(x-1))}}}  [factor out another common factor]<br>
{{{(12/x)(x-1)}}}  [simplify]<br>
I don't know if that was what you were looking for, since you didn't make it clear....<br>
