(z + V2)6+ 26 = 0 Express your solutions in Cartesian form. (b) (1 mark) Use your answer to (a) to express the polynomial P(z) = (z + V2) + 25 as a product of three quadratics with real coefficients. Before you submit your work, take a moment to think about how you might check your answer for this question.] (3) (3 marks) Sketch the following subset of C. A = {z EC : |z |
