a + 2b

Since, information is needed regarding the product, we must only consider 2b.

the answer of a multiplication equation is called product. 

The sign of the product depends on the sign of b.
b = 2 so 22 = 4. the sign of four depends on whether b is positive or negative.

If b is positive then, 2 2 = 4 ; product is positive
if b is negative then, 2 * -2 = -4; product is negative

the sign of a has no bearing on the sign of the product of 2b.
