z^(2)-4z+13=0

If z=3-2i then show that z^(2)-6z+13=0 Hence find the value of z^(4)-4z^(3)+6z^(2)-4z+17

Given z_(1)+3z_(2)-4z_(3)=0 then z_(1),z_(2),z_(3) are

If z_(1),z_(2),z_(3),z_(4) are the roots of equation z^(4)+z^(3)+z^(2)+z+1=0, then prod_(i=1)^(4)(z_(i)+2)

If z is a complex number satisfying z^(4)+z^(3)+2 z^(2)+z+1=0 then |z|=

z is a complex number satisfying z^(4)+z^(3)+2z^(2)+z+1=0 , then |z| is equal to

z is a complex number satisfying z^(4)+z^(3)+2z^(2)+z+1=0 , then |z| is equal to

If z_(1),z_(2),z_(3),z_(4) are the roots of the equation z^(4)+z^(3)+z^(2)+z+1=0, then the least value of [|z_(1)+z_(2)|]+1 is (where [.] is GIF.)

If z=2−3i then z ^2−4z+13=

The sum of the distinct real roots of polynomial 72-36z-26z^(2)+13z^(3)+2z^(4)-z^(5)=0 will be
