1. The term partial fraction is used when decomposing rational expressions into sums. 2. This approach gives rise to weighted rational expressions and weighted automata. 3. Students learn to how write, solve, and graph equations and radicals, and rational expressions . 4. Rational expressions are the quotient field of the polynomials ( over some integral domain ).5. This applies notably to rational expressions over a field. 6. In Math A, students learn to how write, solve, and graph equations and radicals, and rational expressions . 7. Any equation containing fractions or rational expressions can be simplified by multiplying both sides by the least common denominator. 8. The goal is to write the rational expression as the sum of other rational expressions with denominators of lesser degree. 9. The goal is to write the rational expression as the sum of other rational expressions with denominators of lesser degree. 10. In this algebraic context, the regular languages ( corresponding to Boolean-weighted rational expressions ) are usually called " rational languages ".
