Hi Can anyone help, been struggling for hours. (i) given that w=1+2i, express w2, w3, and w4 in the form a+bi. (ii) given that w is a root of the equation z4+pz3+qz2-6z+65=0, find the values of p and q. (iii) write down a second root of the equation. (iv) find the other 2 roots of the equation. Thanks
