if z1 and z2 are 2 complex nos such that z1+z2 is a real number then z2=​

if z1 and z2 are 2 complex nos such that z1+z2 is a real number then z2=​

1 thought on “if z1 and z2 are 2 complex nos such that z1+z2 is a real number then z2=​”

  1. Step-by-step explanation:

    Correct option is

    A

    z2=z1

    for z1z2 to the real

    z2=z1 or−z1

    ⇒z1z2=z1z1=∣z1∣2

    or z1z2=−∣z1∣2

    also

    z1+z2=real

    which isn’t possible for z2=−z1

    for z1−z1=im (z1)

    So,z2=z1
