Question 54826
{{{(sqrt(32x)+sqrt(2x)-sqrt(18x))}}}[Treat each radical as a term.  You can add and subtract like-radicals the same as you would add and subtract like-terms]
.

{{{(sqrt(8*4x)+sqrt(2x)-sqrt(9*2x))}}} [So, try to make the radical terms match]
{{{(4sqrt(2x)+sqrt(2x)-3sqrt(2x))}}} [Simplify]
{{{(4sqrt(2x)+sqrt(2x)-3sqrt(2x))}}}[Since the radicals are now "like-terms" (sqrt(2x)), you can add the coefficients of each radical]
.
{{{(4sqrt(2x)+1sqrt(2x)-3sqrt(2x))}}}[Add the coefficients: 4+1-3=2]
{{{(2sqrt(2x)))}}}
