Answer:

#4 * (sqrt(6) + 2sqrt(10))#

Explanation:

Your starting expression (probably) looks like this

#5sqrt(6) - 4sqrt(10) - sqrt(6) + 12sqrt(10)#

You can regroup the like-terms to get

#5sqrt(6) - sqrt(6) - 4sqrt(10) + 12sqrt(10)#

Now you can factorize like-terms to get

#sqrt(6) * (5 - 1) + sqrt(10) * (12 - 4)#

#4sqrt(6) + 8 sqrt(10)#

All you can do now is factor this expression

#4sqrt(6) + 4 * 2 * sqrt(10) = color(green)(4 * (sqrt(6) + 2sqrt(10)))#
