Rational Root Theorem
For a polynomial equation with integer coefficients, any rational solution (in lowest terms) must satisfy: Key formulas include expressions such as a_n x^n + a_{n-1} x^{n-1} + \cdots + a_1 x + a_0 = 0. This concept is part of Big Ideas Math, Algebra 2 for Grade 8 students, covered in Chapter 4: Polynomial Functions.
Key Concepts
For a polynomial equation $a n x^n + a {n 1} x^{n 1} + \cdots + a 1 x + a 0 = 0$ with integer coefficients, any rational solution $\frac{p}{q}$ (in lowest terms) must satisfy:.
$$\frac{p}{q} = \frac{\text{factor of constant term}}{\text{factor of leading coefficient}}$$.
