# How do you simplify -3sqrt(6x)-3sqrt(6x)?

$- 6 \sqrt{6 x}$

#### Explanation:

To make this look a bit more straightforward, let's substitute $A = \sqrt{6 x}$ and so we can rewrite the statement:

$- 3 \sqrt{6 x} - 3 \sqrt{6 x} = - 3 A - 3 A = - 6 A$

and now we can substitute back in:

$- 6 A = - 6 \sqrt{6 x}$
