If Z_(1),Z_(2) are two complex numbers such that Z_(1)+Z_(2) is a complex no and Z_(1)Z_(2) is real number

If Z1 and Z2 are two complex numbers such that |z1|=|z2|. ls it necessary that z1=z2 ?

If z_1,z_2 are two complex numbers such that Im(z_1+z_2)=0,Im(z_1z_2)=0 , then:

Let z_1 and z_2 be two complex numbers such that z_1+z_2 and z_1z_2 both are real, theb

Let z_(1),z_(2) be two complex numbers such that z_(1)+z_(2) and z_(1)z_(2) both are real, then

Let z_(1),z_(2) be two complex numbers such that z_(1)+z_(2) and z_(1)z_(2) both are real, then

If z_(1) and z_(2) are two complex numbers such that z_(1)+2,1-z_(2),1-z, then
