See a solution process below:

First, remove all of the terms from parenthesis. Be careful to handle the signs of each individual term correctly:

#8k^2 - 14k + 3 - 12k^2 - 5#

Next, group like terms:

#8k^2 - 12k^2 - 14k + 3 - 5#

Now, combine like terms:

#(8 - 12)k^2 - 14k + (3 - 5)#

#-4k^2 - 14k + (-2)#

#-4k^2 - 14k - 2#
