+%28+5sqrt%282%29+%2B+3+%29%2A%28+sqrt%282%29+-+2sqrt%283%29+%29+

ok, multiply out the brackets, as normal:

+5sqrt%282%2A2%29+%2B+3sqrt%282%29+-+10sqrt%282%2A6%29+-+6sqrt%283%29+
+5sqrt%284%29+%2B+3sqrt%282%29+-+10sqrt%2812%29+-+6sqrt%283%29+
+5%2A2+%2B+3sqrt%282%29+-+10sqrt%284%2A3%29+-+6sqrt%283%29+
+10+%2B+3sqrt%282%29+-+10sqrt%284%29%2Asqrt%283%29+-+6sqrt%283%29+
+10+%2B+3sqrt%282%29+-+10%2A2%2Asqrt%283%29+-+6sqrt%283%29+
+10+%2B+3sqrt%282%29+-+20sqrt%283%29+-+6sqrt%283%29+
+10+%2B+3sqrt%282%29+-+26sqrt%283%29+
