-14 sqrt(30 )

Explanation:

This is a binomial separated by a multiplication sign.

To handle this:

  1. multiply everything NOT under the square root signs or radicals
  2. multiply everything under the radicals
  3. combine (by multiplying those two terms together):

-7 xx 2 = -14

sqrt(3) xx sqrt(10) = sqrt(30)

Since sqrt(30) cannot be simplified, -14sqrt(30) is the answer.
