$color(blue)(=-14sqrt6$

$sqrt294$ can be simplified by prime factorising $294$

Here, $294$ is expressed as a product of its prime factors.

$sqrt294=sqrt(2*3*7*7)$

$=sqrt(2*3*7^2)$

$=color(green)(7sqrt6$

So, $-2sqrt294 = -2*color(green)((7sqrt6)$

$color(blue)(=-14sqrt6$

How do you simplify -2sqrt(294)-2sqrt(294)?
