0-44z+3=6+2z

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

Solve the system: x + y - 2z = 0, 2x - 3y + z = 0, 3x - 7y + 10z = 0, 6x - 9y + 10z = 0.

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

(4+z-(3+2z))/(6) =(-z -3 (5-2))/(7) What is the value of z in the equation above ?

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

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

If |z_(1)-2|<2,|z_(2)-4|<4,|z_(3)-6|<6 then |z_(1)+z_(2)+z_(3)| is

If 2z_1-3z_2 + z_3=0 , then z_1, z_2 and z_3 are represented by

If z_1,z_2,z_3 are any three roots of the equation z^6=(z+1)^6, then arg((z_1-z_3)/(z_2-z_3)) can be equal to
