Let's try this.
First, we have the absolute value of -4(-2)-8, or the absolute value of 8-8, so 0.
Let's forget about that, now. It's 0, it adds no value. Let's not worry about it.
For the next, we see the absolute value of -1-(-2)^2
Or:
-1-4, or -5.
Next is 2(-2)^2, or 2(4) = 8.
Therefore, we have -5+8 =3.
If you see any errors, let me know.
Otherwise, I hope this helps!
