Elías and Juanca solve the same problem by posing a quadratic equation. Elijah is wrong when writing the independent term and gets as results of the problem −1-1 and −3-3. Juanca is wrong only when writing the coefficient of the first degree term and gets as results of the problem 1616 and −2-2. What are the correct results of the problem?
