Question 298091
Simplify:
{{{(x-25)/(sqrt(x)-5)}}} Multiply top and bottom by the conjugate of {{{(sqrt(x)-5) = (sqrt(x)-5)*(sqrt(x)+5))}}}
{{{(x-25)(sqrt(x)-5)/((sqrt(x)-5)*(sqrt(x)+5))}}} Simplify the denominator.
{{{cross((x-25))(sqrt(x)+5)/cross((x-25))}}} Cancel the indicated factors leaving you with:
{{{highlight(sqrt(x)+5)}}}
