Answer:

Positive

Explanation:

If thinking in the abstract doesn't work well for you, choose a couple of values that match the description:

a > 0, choose a = 1

b < 0, choose b = -1

Now, the product is ...

-4ab = (-4)(1)(-1) = 4 . . . a positive product

__

The product will be positive when the total number of minus signs of the factors is even. Here, there are 2 minus signs, so the product is positive.
