You can put this solution on YOUR website!
Enter it like this: sqrt(#)
sqrt%2863%29+-+sqrt%2828%29+%2B+5%2Asqrt%287%29
sqrt%289%2A7%29+-+sqrt%284%2A7%29+%2B+5%2Asqrt%287%29
sqrt%289%29%2Asqrt%287%29+-+sqrt%284%29%2A+sqrt%287%29+%2B+5%2Asqrt%287%29
factor out sqrt%287%29 from each term
sqrt%287%29%2A%283+-+2+%2B+5%29
6%2Asqrt%287%29
Thats it, unless I goofed
