Answer:
Step-by-step explanation:
We can write the following system of equations:
Adding both equations together, we isolate and get:
Plugging in any of the equations, we can solve for
:
Verify that the solution pair works
Therefore, the two numbers are .
Following expressions will have negative product
Following expressions will have positive product
Further explanation:
We will see at each expression one by one
First expression is:
In the given expression one term is positive and one term is negative. The product of negative and positive terms is negative.
Second Expression is:
Both terms are negative and the product of two negative terms is positive.
Third Expression is:
