Rational function — In mathematics, a rational function is any function which can be written as the ratio of two polynomial functions. DefinitionsIn the case of one variable, x , a rational function is a function of the form: f(x) = frac{P(x)}{Q(x)}where P and Q are … Wikipedia
Rational root theorem — In algebra, the rational root theorem (or rational root test to find the zeros) states a constraint on solutions (or roots) to the polynomial equation:a nx^n+a {n 1}x^{n 1}+cdots+a 0 = 0,!with integer coefficients.Let a 0 and a n be nonzero.Then… … Wikipedia
Polynomial long division — In algebra, polynomial long division is an algorithm for dividing a polynomial by another polynomial of the same or lower degree, a generalised version of the familiar arithmetic technique called long division. It can be done easily by hand,… … Wikipedia
