(Section 0.6: Polynomial, Rational, and Algebraic Expressions) 0.6.4 PART F: RATIONAL AND ALGEBRAIC EXPRESSIONS A rational expression in x can be expressed in the form: polynomial in x nonzero polynomial in x Example Set 3 (Rational Expressions) Examples of rational expressions include: a) 1 x . b) 5 x 3 ± 1 x 2 + 7 x ± 2 . Irrational coefficients such as ± 2 are permissible as coefficients of either polynomial. c) x 7 + x which equals x 7 + x 1 ± ² ³ ´ µ . In fact, all polynomials are rational
