Summing to zero means the two numbers are additive inverses, i.e. negatives of each other. We choose the pair of negations:
Answer: -3, 3
Answer:
A
Step-by-step explanation:
441 is odd, so we can't divide it by 2.
Since the sum of its digits is
, which is divisible by 3, we can divide 441 by 3, and we have

Which is still divisible by 3, because
. We have

49 is not divisible by 3 anymore, nor by 5 (it doesn't end with 0 or 5).
It is divisible by 7 though, we have

and finally,

So, the factorization of 441 is

The definition of a coefficient is the number BEFORE the variable. So in 76x^2, the coefficient is 76.<span>
