Let X and y be real numbers, and x1 − I + Y1 − 2I = 51 − 3I, then x + y=______ .
X1 − I + Y1 − 2I = x (1 + I) 2 + y (1 + 2I) 5 = (x2 + Y5) + (x2 + 2y5) I, and 51 − 3I = 5 (1 + 3I) 10 = 12 + 32i, so x2 + Y5 = 12 and X2 + 2y5 = 32, the solution is x = - 1, y = 5, so x + y = 4

Let z = a + bi, then (a + bi) ² = a-bia & #178; + 2abi + (BI) ² = a-bi (A & #178; - B & #178;) + 2abi = a-bi, so 1, a & #178; - B & #178; = a, 2, 2Ab = - B from formula 2, when B = 0, 2Ab = - B, substituting formula to get a & #178; = a, a = 0 or 1 from formula 2, when B ≠ 0, 2A =
(a + bi) ^ 2 = a-bi to get a = 0 is pure imaginary number
