(√3x+2)(√3x-2) Answer by stanbon(75887) (Show Source):
You can put this solution on YOUR website! (√3x+2)(√3x-2)
---------
Use FOIL and you will get the product which is the difference of two squares:
F: sqrt3x*sqrt3x = 3x
O: sqrt3x *-2 = -2sqrt3x
I: sqrt3x * 2 = 2sqrt3x
L: 2*-2 = -4
--------
Add those up and you will get
3x-4
