Question 39954: Please tell me if I'm doing this right!
The instructions are to simplify the radical expression.
The problem is (sqrt3 + 5)(sqrt3 - 3)
Using the foil method I come up with:
sqrt3 * sqrt3 -3sqrt3 + 5sqrt3 - 15
= 3 - 3sqrt3 + 5sqrt3 - 15
= -12 + 2sqrt3
Is this right and does it need (or can it be) simplified further?
