Simplify 2 sqrt 12 2 sqrt2 sqrt8 I need the answer step by

Simplify 2 sqrt 1/2 + 2 sqrt2 - sqrt8. I need the answer step by step so don\'t condense the answer. Someone answered this already but there where a few errors on both of our parts. The terms are 2 sqrt1/2 + 2sqrt2 - sqrt 8

Solution

We have 2( ½) + 22 - 8 = ( 4/2) + 22 - (4*2) ( as 2 = 4 and 8 = 4*2)

Or, 2( ½) + 22 - 8   = 2 + 22 - 22 [ as 4/2 = 2 and (4*2) = (4) * (2) = 22 ]

Or, 2( ½) + 22 - 8   = 2
