Sorry, it should have been cubed, not squared.
-3(12)-[5(-4)-2cubed]
It is 2 to the third power (is that cubed?)

Without the correction, your answer would have been -12. With your correction (cubed rather than squared) your answer should be: -8
Here are the parts:
-3(12) = -36
5(-4) = -20
2 cubed (2^3) = 2 x 2 x 2 = 8
So it simplifies to:
-36 - (-20 - 8)
This further simplifies to:
-36 - (-28)
Which finally simplifies to:
-36 + 28
= -8
Whew! Lot's of negatives to keep track of! Google confirms the answer in the link below:

-3(12)-[5(-4)-2squared]
= -3(12)-[-20-4]
= -36-(-24)
= -36 + 24
= -12

-3(12)= -36
5(-4)= -20
2CUBED= 8
sooo
-36-[-20-8]=
-36-[-28]=
-36+28=
-8= Your final answer

- 3(12) - [5(- 4) - 2² ]
- 36 - [ - 20 + 4 ]
-36 - [ - 16 ]
- 36 + 16
- 20
The answer is - 20
