Find in Cartesian form all square roots of the complex number w = -3 + 4i. (Hint: write z = x + zy, compute z, and find x, y that solve the equation z = -3 + 4i). Give your answer as a list of complex numbers separated by a semi-colon, for example, 1+2*I; 3+4*I. The order of the numbers in your list is not important. Answer: the square roots of w are Hence or otherwise, find all solutions of the quadratic equation z~ + (2 - 62) z - 5 - 10i = 0. Give your answer as a list of complex numbers separated by a semi-colon, for example, 1+2*I; 3+4*I. The order of the numbers in your list is not important. Answer: the solutions of the equation are
