Any simplification problem can be solved by following the BEDMAS law* : Brackets, Exponents, Division, Multiplication, Addition, Subtraction. Work in this order and you'll get it right.

First, expand all the brackets by multiplying the outside term with each of the inside ones, working from the inside out:

Now add like terms, and expand again:
#-50-2[9-6f] = -50-18+12f#

Then just add like terms again:

And that's the answer! Remember that when multiplying positives and negatives, the answer is positive if the the signs are the same, and negative if they're different.
