Solve the Complex Equation: Modulus of z + 4 Equals 12

Question

z+4=12 \left| z + 4 \right| = 12

Step-by-Step Solution

To solve z+4=12 \left| z + 4 \right| = 12 , consider the two cases:

1. z+4=12 z + 4 = 12 gives z=8 z = 8

2. z+4=12 z + 4 = -12 gives z=16 z = -16

Thus, the solutions are z=8 z = 8 and z=16 z = -16 .

Answer

z=16 z = -16 , z=8 z = 8
