+2sqrt%285%29+%2A+%283sqrt%282%29+%2B+sqrt%2845%29+-+4sqrt%285%29+%29+
Break down the rt45
+2sqrt%285%29+%2A+%283sqrt%282%29+%2B+3sqrt%285%29+-+4sqrt%285%29+%29+
Add like terms within the ( )
+2sqrt%285%29+%2A+%283sqrt%282%29+-+1sqrt%285%29+%29+
Distribute the 2rt5
+%282sqrt%285%29+%2A+3sqrt%282%29%29+-+%282sqrt%285%29+%2A+1sqrt%285%29%29+
+6sqrt%2810%29+-+1sqrt%2825%29+
work out the 2nd root
+6sqrt%2810%29+-+5+
