%289m%5E2n+-+8mn+%2B+4mn%5E2%29+-+%287m%5E2n+%2B+6mn+-+7mn%5E2%29
9m%5E2%2An+-+7m%5E2%2An+-+8m%2An+%2B+6m%2An+%2B+4m%2An%5E2+-+7m%2An%5E2
2m%5E2%2An+-+2m%2An+-+3m%2An%5E2
m%2A%282m%2An+-+2n+-+3n%5E2%29
m%2An%2A%282m+-+2+-+3n%29
2,-2,and -3 are coefficients
There are no constants
m and n are the variables
Maybe they want something else, but
I don't know what it could be
