Calculation of (a-b-c) (B + C-A) &# 178; (C-A + b) &# 179; process

(a-b-c)(b+c-a)²(c-a+b)³=(a-b-c)(c-a+b)^5
=(a+b-c-2b)(c-a+b)^5
=-(c-a+b)^6-2b(c-a+b)^5

1. The solution of the equation a (x + m) &# 178; + B = 0 is X1 = - 2, X2 = 1, then the solution of the equation a (x + m + 2) &# 178; + B is——
2. The turnover in January is 2 million yuan, and the total turnover in the first quarter is 10 million yuan. If the average annual growth rate is x, the equation should be——

1) Let x + 2 = y, then equation a (x + m + 2) & #178; + B becomes a (y + m) ^ 2 + B = 0, because the solution of equation a (x + m) & #178; + B = 0 is X1 = - 2, X2 = 1, so the solution of equation a (y + m) & #178; + B = 0 is Y1 = - 2, y2 = 1, when Y1 = - 2, that is, x + 2 = - 2, the solution is X1 = - 4, when y2 = 1, that is, x + 2 = 1, the solution is
