If z_1and z_2 are any two complex numbers show that `|z_1+z_2|^2+|z_1-z_2|^2=2|z_1|^2+2|z_2|^2`

Write any two complex numbers,then show that |z1+z2|^2+|z1-z2|^2=2(|z1|^2+|z2|^2)

If z_1 , and z_2 be two complex numbers prove that |z_1+z_2|^2+|z_1-z_2|^2=2[|z_1|^2+|z_2|^2]

If z_1 and z_2 (ne 0) are two complex numbers, prove that : |z_1 z_2|= |z_1||z_2| .

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

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

For any two complex numbers z_1 and z_2 prove that: |\z_1+z_2|^2 +|\z_1-z_2|^2=2[|\z_1|^2+|\z_2|^2]

For any two complex numbers z_1 and z_2 , we have |z_1+z_2|^2=|z_1|^2+|z_2|^2 , then

For any two complex numbers z_1 and z_2 , we have |z_1+z_2|^2=|z_1|^2+|z_2|^2 , then

If z_1 and z_2 are two complex numbers such that |\z_1|=|\z_2|+|z_1-z_2| show that Im (z_1/z_2)=0
