WebThe constant in the polynomial 12x + 19y - 1 is -1. You include the sign that appears next to the number. However, if it was 12x +19y +1 , then the constant will be +1 but in mathematics, the positive signs need not be written (if it is a number appearing on its own in an answer), so the answer for my above polynomial is 1.
