" (ii) "6z^(2)-3z+5=0

Solve for z : z^(2) - 6z + 6 = 0 .

Let z_(1), z_(2), z_(3) be the roots of iz^(3) + 5z^(2) - z + 5i = 0 , then |z_(1)| + |z_(2)| + |z_(3)| = _____________.

If z is a complex number satisfying the equaiton z^(6) - 6z^(3) + 25 = 0 , then the value of |z| is

If z is a complex number satisfying the equaiton z^(6) - 6z^(3) + 25 = 0 , then the value of |z| is

If z = 3 + 2i , prove that z^(2) - 6z + 13 = 0 and hence deduce that 3z^(3) - 13z^(2) + 9z + 65 = 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

If z = i(i + sqrt(2)) , then value of z^(4) + 4z^(3) + 6z^(2) + 4z is

If x=4z^(2)+5, y=6z^(2)+7z+3 , find (d^(2)y)/(dx^(2)) .

Divide: 5z^(3)-6z^(2)+7z by 2zsqrt(3)a^(4)+2sqrt(3)a^(3)+3a^(2)-6a by 3a
