#-12sqrt5#

#2sqrt5xx# #-3sqrt4#

Multiply the coefficients and the square roots together

which would be, #2xx(-3)##(sqrt5xxsqrt4#)

or, #-6xxsqrt5xx2# (because#sqrt4# is #2#)

or, #-12sqrt5#

The Answer is -12#sqrt(5#

Always remember to factor the #sqrt(4#. After that, multiply the numbers that are outside the square roots. so 2 #*# -6. just add the #sqrt(5#
