Answer:

Step-by-step explanation:

hello :

3x(x-y+z) + 2y (x+y-z) = 3x²-3xy+3xz +2yx+2y²-2yz

3x(x-y+z) + 2y (x+y-z) = 3x² -xy+3xz -2yz+2y²

Answer:

3x^2 + 3xz + 2y^2 - 2yz - xy

Step-by-step explanation:

(1) multiply it to get

3x^2 - 3xy + 3xz and 2yx + 2y^2 - 2yz

add similar variables (-3xy + 2yx)

( the order of the variables doesn't matter xy or yx is the same)

we get -xy

and then after that simplifying we get 3x^2 + 3xz + 2y^2 - 2yz - xy
