If z1, z2, z3 are three complex numbers such that 4z1 – 7z2 + 3z3 = 0, then z1, z2, z3 are
z2 divides the join of z1 and z3 in the ratio 3 : 4.
Sum of the common roots of
If z1 and z2 lie on the same side the line
If z1 and z2 are the roots of the equation z2 +az +b = 0, then prove that the origin, z1 and z2 from an equilateral triangle if and only if
The number of complex numbers satisfying the equation |z| = 2 and |z| =|z – 1| is
And z2 + 1 is
If z2/(z – 1) is always real, then z can lie on
