Question 94371
Simplify? We don't like to see radicals in the denominator, so...
{{{2/((3+sqrt(5)))}}} Multiply the numerator and the denominator by conjugate of the denominator which is ({{{3-sqrt(5)}}}).
{{{2(3-sqrt(5))/(3+sqrt(5))(3-sqrt(5))}}} Simplify the denominator.
{{{2(3-sqrt(5))/(9-(sqrt(5))(sqrt(5)))}}} Simplify some more.
{{{2(3-sqrt(5))/(9-5)}}}
{{{2(3-sqrt(5))/4}}} Cancel a 2 in the top & bottom.
{{{(3-sqrt(5))/2}}}
