Please explain adding/subtracting radical expressions to me.?
for adding and subtracting you need the same root (in this case 2) then you simply add the numbers you would multiply to the root(3s in this case) so 3+3=6 making it 6 times the square root of 2. You would do the exact same thing with subtraction, but simply subtract the numbers you would multiply to the roots For more help go here… http://regentsprep.org/regents/Math/radi…
