3x2y - x2y
if you understood the method of the other problem apply it here get the constant 3-1 then keep the x then do the samr with the y
\[3x^2y-x^2y\] if it helps you can look at this as a variable \[x^2y\] thus it becomes \[3z-z\] which makes the answer 2z if z =x^2 y and the answer should be \[2x^2y\]
i didn't understand the method to the other problem neither .
you have to get your constants for example here is 3 and 1 if you separate the constants and your variables as the person above did it can help you group the variables
