Show your common denominators and numerators on this sheet or separate paper. To solve equations involving rational expressions, we have the freedom to clear out fractions before proceeding. In mathematics, a rational function is any function which can be defined by a rational fraction, which is an algebraic fraction such that both the numerator and the denominator are polynomials.The coefficients of the polynomials need not be rational numbers; they may be taken in any field K.In this case, one speaks of a rational function and a rational fraction over K. Any fraction with non-zero denominators is a rational number. 1 HiSET® Math Khan Academy® Instructional Support Videos and Exercises The HiSET® program has identified videos and exercises available at www.khanacademy.org to support HiSET Math test preparation. f(x) = 2x <<2caac4fa56be664c93ec91f6c74b2925>]>> This, we believe shall be useful in preparing and gearing up for taking the exams.
