Let Z satisfy the absolute value of 2Z + 15 = the root sign 3 times the absolute value of conjugate + 10 of Z, and find the Mo value of Z


Let z = a + bi
The conjugate of / 2Z + 15 / = (2a + 15) ^ 2 + 4B ^ 2 / Z + 10 / = √ (a + 10) ^ 2 + B ^ 2
The conjugate of ∵ / 2Z + 15 / = √ 3 / Z + 10/
Two sides square
(2a+15)^2+4b^2=3[(a+10)^2+b^2]
It is reduced to a ^ 2 + B ^ 2 = 75
And / Z / = √ (a ^ 2 + B ^ 2) = √ 75 = 5 √ 3
