- The incorrect value in the table is -2y
- The correct value is -2xy
<h3>How to determine the incorrect value</h3>
From the table, we have the following product
2x* -y = -2y
or
-y * 2x =-2y
The above equation is incorrect.
This is so because, the product of 2x and -y is -2xy, not 2y
Hence, the incorrect value in the table is -2y and the correct value is -2xy
