What is the simplest form of the radical expression?3 2a−−√3−6 2a−−√3

To simplify the given radical expression, we can combine the two radicals:

√(3) - 6√(3)

Since both radicals have the same term (√(3)), we can combine them by subtracting the coefficients:

(1 - 6)√(3)

Simplifying the coefficients gives us:

-5√(3)

So, the simplest form of the radical expression is -5√(3).
