(a+5)+(b-1)i=7-3i

(a + 5) + (b - 1) i = 7 - 3 i

a = 2, b = - 2

Solution steps

(a + 5) + (b - 1) i = 7 - 3 i

Complex numbers can be equal only if their real and imaginary parts are equalRewrite as system of equations:

[a + 5 = 7 b - 1 = - 3]

[a + 5 = 7 b - 1 = - 3] : a = 2, b = - 2

a = 2, b = - 2

z^{2} + 4 i z + 5 = 0

\frac{2 + 5 i}{1 - i} = x + y i

a, ∣ a + bi ∣ = 1

a, ∣ a + bi ∣ = 3

i (x) = x^{2} + 4 x + 7
