If we multiply or divide both sides of an inequality by the same negative number, we ...To solve a rational expression start by simplifying the expression by finding a common factor in the numerator and denominator and canceling it out. Then, check for extraneous solutions, which are values of the variable that makes the denominator equal to zero. These solutions must be excluded because they are not valid solutions to the equation.
