= -4xy + 3x2y - 3xy2 + 7 - 3x2y - 2xy + 2xy2 - 4
= -4xy -2xy + 3x2y - 3x2y - 3xy2 + 2xy2 + 7 - 4
= -6xy - xy2 + 3
It is very special when -M - G = -G - M. The math problem is interesting and interesting

We have : -M - G = -(3x2y + 2xy - 2xy2 + 4) - (4xy - 3x2y + 3xy2 - 7)
= -3x2y - 2xy + 2xy2 - 4 - 4xy + 3x2y - 3xy2 + 7
= -3x2y + 3x2y - 2xy - 4xy + 2xy2 - 3xy2 - 4 + 7
= -6xy - xy2 + 3
Peace of mind 100%
