<u>Answer:</u>
Zero
<u>Step-by-step explanation:</u>
We are given the following expression and we are to determine what is the sign of its product:

One of the three terms in the expression is positive while one is negative. So if we start multiplying the two terms from the left side. we will get a negative number.
But when we will multiply it with zero, the whole product will become zero as anything times zero is always zero. Therefore, answer will be zero.
Answer:
Step-by-step explanation:
