When multiplying an odd number of factors,, then that means they will equal a negative. This rule will make this expression change to the following:
-
x × 5y × 2x
Now reduce the numbers with 5
-2xy × 2x
Lastly,, calculate the product to get your final answer
-4x²y
This means that your coefficient is -4 and the simplified version of your expression is -4x²y.
Let me know if you have any further questions
