You can put this solution on YOUR website! your equation is sqrt(x) / (3 + sqrt(x))
multiply numerator and denominator by (3 - sqrt(x))
this will remove sqrt(x) from the denominator.
the numerator will become sqrt(x) * (3 - sqrt(x) which will become 3*sqrt(x) - x.
the denominator will become (3 - sqrt(x)) * (3 + sqrt(x)) which will become 9 - x.
the resulting fraction will be (3*sqrt(x) - x) / (9 - x).
