@ParthKohli @Legends @mathmate @welshfella

OpenStudy (phi):

green did it correctly, but the usual (standard order) is to write the terms starting with the highest exponent first.

OpenStudy (phi):

in other words, you can order the 4 terms in greens's answer any way you like. but the standard way is to write the order this way \[ 6x^3+3x^2y+2xy+y^2\]

OpenStudy (phi):

that is alphabetical (so x goes first) biggest exponent down to smallest.

OpenStudy (countrygirl1431):

ok thats what i thought it was but i wasnt quite sure

OpenStudy (phi):

when you add (and we are adding) we can change their order

OpenStudy (countrygirl1431):

ok thanks @phi
