Question 75897: Ok so this is an algebra 2 question, but i couldnt find anything about roots in the algebra 2 section so i figured i would ask it here. I am not exactly sure how to type a square root on a computer so substiture the divisiont mark (/) as a square root symbol, but here goes:
/-6 x /-15 when i asked my teacher she told me to start out by changing it to:
i/6 x i/15 but i am stumped after this part. Sorry if my question is somewhat confusing because i cant type a square root but thx for this wonderful site and all your help i would probably be failing if it wasnt for you guys.

+sqrt%28-6%29+%2A+sqrt%28-15%29+
+%28i%29sqrt%286%29+%2A+%28i%29sqrt%2815%29+
now ... i * i = i^2 = -1
+-1sqrt%286%2A15%29+
Factor out 6 and 15
6 = 3 * 2
15 = 3 * 5
6 * 15 = 2 * 3 * 3 * 5
+-1sqrt%282%2A3%2A3%2A5%29+
Take out the pairs
+-1%283%29sqrt%282%2A5%29+
Multiply
+-3sqrt%2810%29+
