: Good evening tutor,
Could you explain to me how to solve this problem. I am sure the answer I keep getting is incorrect but I am not sure where my confusion is.
Simplify each radical expression:
(sqrt of 3 + 5) (sqrt of 3 - 3)
Thank you so much for your help.

(sqrt of 3 + 5) (sqrt of 3 - 3)
-------------------
Use FOIL:
F: [sqrt3][sqrt3] = 3
O: [sqrt3][-3]= -3sqrt3
I: [sqrt3][5] = 5sqrt3
L: 5[-3]= -15
-----------------
Combine these to get:
-12 +2sqrt3
=========================
Cheers,
