(UECE 2026.2-1ª Fase) A forma geral de um número complexo z é z = x + iy, onde x e y são números rea

(UECE 2026.2-1st Phase) The general form of a complex number z is z = x + iy, where x and y are real numbers, and i is the complex number whose square is equal to -1. In a plane equipped with the usual orthogonal Cartesian coordinate system, the complex number z = x + iy can be identified with the ordered pair (x, y). With this identification, the expression (4 + 6i)/(1 - i) will be identified with: A) (1, 3). B) (1, 5). C) (-1, 5). D) (-1, 3).
