Because m and n satisfy the equation X 2-X = 3 at the same time, and these two numbers are not equal, then the two roots of the equation are m and n, because the formulas to be solved later are not symmetrical, so there may be more than one answer, which has a sequential relationship.

Replace n 2 with 3+n (because N2-n = 3；; N 2 = 3+n), then the original formula is equal to

2(3+n)-Mn+2m+20 16 = 2(m+n)-Mn+2022

According to Vieta's theorem (for the relationship between roots and coefficients, we might as well first identify m=x 1, n=x2).

Mn=-3, m+n= 1, (only a pair of unique answers)

Original formula: 2* 1+3+2022=2027.
