Question

3x2y - x2y

Answer 1

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

Answer 2

\[3x^2y-x^2y\]
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
\[2x^2y\]

Answer 3

i didn't understand the method to the other problem neither .

Answer 4

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

Answer 5

okay i got it
