Answer:
-3/2
Explanation:
Here we have an ambiguous notation. Hence, I assume you mean (-12/((3 x (-8+ (-4)^2 -6) +2), which is the one that makes more sense.
First, we work the arithmetic on the denominator (D).
D= 3 x (-8 + (-4)^2 - 6) + 2
D=3 x (-8 + (-4) x (-4) -6) + 2
D= 3x (-8 +16 -6) + 2
D= 3 x (2) + 2=6 + 2=8
Now, we just have to divide -12 by D to obtain the answer.
-12/D = -12/8 =(-2 x 2 x 3)/(2 x 2 x 2) = -3/2
