WebWhat is a polynomial? A polynomial is a mathematical expression consisting of variables and coefficients, that involves only the operations of addition, subtraction, and … The nature (real or not, distinct or not) of the roots of a cubic can be determined without computing them explicitly, by using the discriminant. The discriminant of a polynomial is a function of its coefficients that is zero if and only if the polynomial has a multiple root, or, if it is divisible by the square of a non-constant polynomial. In other words, the discriminant is nonzero if and only if the polynomial is square-free. churches selling pumpkins near me https://hartmutbecker.com
