Question 798381
Multiply top and bottom by {{{2+sqrt(x)}}}, which is the conjugate of the denominator, to get...


{{{3/(2-sqrt(x))}}}


{{{(3(2+sqrt(x)))/((2-sqrt(x))(2+sqrt(x)))}}}


{{{(3(2+sqrt(x)))/(2^2-(sqrt(x))^2)}}}


{{{(3(2+sqrt(x)))/(4-x)}}}


{{{(3*2+3*sqrt(x))/(4-x)}}}


{{{(6+3*sqrt(x))/(4-x)}}}
