Description
There is more than one approach to solving a rational equation, and this section explores two such methods. The first method is to multiply both sides by the common denominator to clear fractions. The second method is to find equivalent forms of all expressions with a common denominator, set the numerators equal to each other, and solve the resulting equation. Either approach requires keeping an eye out for extraneous solutions; in other words, values that appear to be a solution to the equation but cause division by zero and are, thus, not valid.
