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....
or powers. Many times, problems will require you to use the laws of exponents to simplify variables with exponents, or you will have to simplify an equation with exponents to solve it. To work with exponents, you need to know the basic exponent rules. ...
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...
