Question 65691
Perform the division, rationalize the denominator if necessary, then simplify

6 - sqrt20 / 2

If this is what you mean:
{{{(6-sqrt(20))/2}}}
{{{(6-sqrt(4)*sqrt(5))/2}}}
{{{(6-2*sqrt(5))/2}}}
{{{2(3-sqrt(5))/2}}}
{{{highlight(3-sqrt(5))}}}
:
If that's not what you meant, let me know and I'll edit this.
Happy Calculating!!!
