The answer you are looking for is -891.

Solution/Explanation:

Writing out the expression first

-2-7{3+4[(-5)²+6]}

Simplifying (-5)², which is 25, since (-5)(-5)=25

-2-7[3+4(25+6)]

Simplifying 25+6, which is 31

-2-7[3+4(31)]

Simplifying 4(31), which is 124

-2-7(3+124)

Simplifying 3+124, which is 127

-2-7(127)

Simplifying -7(127), which is -889

-2-889

Finally, you will get -891.

So, therefore, the final answer to this problem is -891.
