z₂ = 2 - 5i,
z₃ = 1 - 2i
ditanyakan z₁ + z₂z₂ - z₃
bilangan imajiner i = √(-1), berarti i² = - 1
coba hitung dulu z₂z₂ = [2 - 5i][2 - 5i]
z₂z₂ = 4 - 10i - 10i + 25(- 1) = - 21 - 20i
menuju target z₁ + z₂z₂ - z₃ = 5 + 3i + (- 21 - 20i) - (1 - 2i)
z₁ + z₂z₂ - z₃ = 5 - 21 - 1 + 3i - 20i + 2i
z₁ + z₂z₂ - z₃ = - 17 - 15i
