Depends.
A. -12 - -6 = -6
but
B. -6 - -12 = 6
Two negatives always cancel, so the equation for A. would be like saying
-12+6, and B. -6+12.
Answer: 
Step-by-step explanation:
Factor theorem : If x=a is a zero of a polynomial p(x) then (x-a) is a factor of p(x).
Given: Zeroes of polynomial : -4,0, 1, and 4.
Then Factors =
[By factor theorem ]

Multiplying these factors to get polynomial in standard form.

Hence, B is the correct option.
