What is the product of the complex number z1 and it’s conjugate? PLEASE HELP GRAPH in picture
12345 [234]

Answer:

The product is 25

Step-by-step explanation:

we know that

The complex number z1 is equal to

z1=(-4-3i)

we know that

To find the complex conjugate of (-4 - 3i) we change the sign of the imaginary part

so

The conjugate is equal to (-4+3i)

therefore

(-4-3i)(-4+3i)=16-9(-1)=25
