Rational expressions contain fractions with polynomials in both the numerator and the denominator. Solving rational expression equations requires more work than solving standard polynomial equations because you have to find the common denominator of the rational terms, then simplify the resulting expressions....
If there is no equal sign between the expressions, it is a rational expression. Otherwise, as mentioned above, it is a rational equation. Observe these examples: x2+x2x2−3x+4x2+x2x2−3x+4=x2x−1ExpressionEquationHow to Solve Rational Equations Rational Equation Examples Lesson Summary...
