This lesson teaches us how to solve rational equations by eliminating the denominator from the equation. By multiplying both sides by a common denominator, the equation can be simplified and solved using the zero product rule. The zero product rule states that when two factors are multiplied together and the answer is 0, one or both of the quantities are equal to 0. This allows us to solve for the values of x and check that the statement is true.
Solving rational equations where both sides of the equation are multiplied by the common denominator in order to eliminate the denominator from the equation.
