note that since there are 2 distinct integer roots to that, it is a second degree polynomial, and that makes have a degree of 0, otherwise, there would be a higher degree
tandaan na since may 2 hiwalay integer pinagmulan iyon, ito ay isang ikalawang polinomyal degree, at na gumagawa ng magkaroon ng isang antas ng 0, sa kabilang banda, may magiging isang mas mataas na antas
