Please help me with this equation. I do not have the right answer and I don't know where I am going wrong.

-2 to the second power (-2 -x) - x to the zero power (3-2) = -2(x+3)

The correct answer is -13 over 6. I keep getting -3 over 2.

Where am I going wrong? Any help would be greatly appreciated. Thank you!

I would help u but I can not understand what the equation looks like by your writing

I don't understand it.. What's x?
