Rational Root Theorem Calculator
The Rational Root Theorem is a helpful tool in algebra that allows us to find possible rational roots of a polynomial equation. This theorem states that any rational root of a polynomial equation has the following properties: it is a factor of the constant term divided by a factor of the leading coefficient. By utilizing the Rational Root Theorem in conjunction with synthetic division or the factor theorem, we can simplify the process of finding roots of polynomial equations.
What is the Rational Root Theorem?
The Rational Root Theorem is a fundamental principle in algebra that helps us determine the possible rational roots of a polynomial equation. It states that if we have a polynomial equation of the form:
f(x) = anxn + an-1xn-1 + … + a1x + a0
Where an, an-1, …, a1, a0 are integer coefficients, then any rational root of the equation must be of the form p/q, where p is a factor of a0 and q is a factor of an.
