Question 919646
your equation is:


{{{(2x-1) / (sqrt(2x)-1)}}}


multiply the expression by {{{(sqrt(2x)+1) / (sqrt(2x) + 1)}}} to get:


{{{(2x-1) / (sqrt(2x)-1)}}} * {{{(sqrt(2x)+1) / (sqrt(2x) + 1)}}} = {{{((2x-1)*(sqrt(2x)+1)) / ((sqrt(2x)-1)*(sqrt(2x)+1))}}}


this simplifies to {{{((2x-1)*(sqrt(2x)+1)) / (2x-1)}}}


the (2x-1) in the numerator and the denominator cancel out and you are left with:


{{{sqrt(2x)+1)}}}
