I get 14:-1, but may be misreading the question.

Explanation:

I'm answering the question:
Find [(-2)^15+(-2)^12]:[(-2)^11+(-2)^12] in its simplest form.
If this is not the question you intended, please correct me!
Dividing both sides of the ratio by (-2)^11 gives:
[(-2)^4+(-2)]:[1+(-2)]
Applying the indices gives:
[16+ -2]:[1+ -2]=14: -1
