How do I factorise this

x²y-2x²z+2y²z-3xy²

Nothing worthwhile can be done here

Wolfram agrees with me:

Okay thank you reiny....done my best was almost going crazy.....

To factorize the expression x²y - 2x²z + 2y²z - 3xy², you can follow these steps:

Step 1: Look for any common factors between the terms. In this case, the common factor is "xy".
x²y - 2x²z + 2y²z - 3xy² = xy(x - 2z + 2yz - 3y)

And that's the factored form of the expression!
