College Algebra (MindTap Course Li... 12th Edition. Rational Zero Theorem. The Rational Zeros Theorem. The steps to find the solution for rational inequality is as follows: Rewrite the given rational inequality such that the right-hand side of the inequality is zero. After completing this tutorial, you should be able to: List all possible rational zeros using the Rational Zero Theorem. The Rational Zeros Theorem states: If P(x) is a polynomial with integer coefficients and if is a zero of P(x) (P() = 0), then p is a factor of the constant term of P(x) and q is a factor of the leading coefficient of P(x). College Algebra (MindTap Course Li... 12th Edition. … Here’s how it … We can use the Rational Zeros Theorem to find all the rational zeros of a polynomial. Exercise 1 List all of the possible rational zeros for each of the following polynomials: $$f(x) = x^3 - 7x^2 + 7x + 15$$ $$f(x) = x^4 - 4x^3 - 13x^2 + 4x + 12$$ $$f(x) = x^5 - 3x^4 + 7x^2 + 10$$ $$f(x) = 2x^3 - 6x^2 + 5x - 8$$ \(f(x) = … 8. The Rational Root Theorem. In algebra, the rational root theorem (or rational root test, rational zero theorem, rational zero test or p/q theorem) states a constraint on rational solutions of a polynomial equation + − − + ⋯ + = with integer coefficients ∈ and , ≠. Solutions of the equation are also called roots or zeroes of the polynomial on the left side. Use the Rational Zero Theorem to list all possible rational zeros for the given function Since all coefficients are integers, we can apply the rational zeros theorem. Not every number in the list will be a zero of the function, but every rational zero of the polynomial function will appear somewhere in the list. R. David Gustafson + 1 other. Rational inequality is a combination of rational expression and inequality. Do Not Include" =" In Your Answer. When the leading coefficient is not 1, the list of possible rational zeros can increase dramatically. The Rational Zero Theorem helps us to narrow down the number of possible rational zeros using the ratio of the factors of the constant term and factors of the leading coefficient of the polynomial. Equivalently, the theorem gives all possible rational roots of a polynomial equation. The following diagram shows how to use the Rational Root Theorem.
