1 Drag each tile to the correct box. Not all tiles will be used. One solution each is given for four quadratic equations. Assuming that each quadratic equation has two solutions, what is the second solution for each equation? I - 4+5i I = -5 - 41 I = 5 + 4i r = 4 - 51 1 = 5 – 4i 4 + 5i I = -4 - 51 Reset Next
