$- 14 \sqrt{30}$ $-14 sqrt(30 )$

Explanation:

This is a binomial separated by a multiplication sign.

To handle this:

multiply everything NOT under the square root signs or radicals

multiply everything under the radicals

combine (by multiplying those two terms together):

$- 7 \times 2 = - 14$ $-7 xx 2 = -14$

$\sqrt{3} \times \sqrt{10} = \sqrt{30}$ $sqrt(3) xx sqrt(10) = sqrt(30)$

Since $\sqrt{30}$ $sqrt(30)$ cannot be simplified, $- 14 \sqrt{30}$ $-14sqrt(30)$ is the answer.
