Given the formula 2m & # 178; - (+) + Mn & # 178;, fill in the appropriate formula in the brackets, so that the result after merging the similar terms is 2, and the polynomial you write is - I don't know --

Given the formula 2m & # 178; - (+) + Mn & # 178;, fill in the appropriate formula in the brackets, so that the result after merging the similar terms is 2, and the polynomial you write is - I don't know --

2m²-(2m²+nm²+2)+mn²=2
