$12 f - 68$

Explanation:

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:
$- 50 - 2 \left[3 - 3 f + 6 - 3 f\right]$

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

Then just add like terms again:
$12 f - 68$

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.
