(1) When solving a rational equation what is the first step we must always take? Illustrate using the example 2/w + 3/5 = 5/6 how you clear the rational equation of fractions.
(1) When solving a rational equation what is the first step we must always take? Illustrate using the example
(2) After solving a rational equation, why is it important to check your answer? How is this done? What happens if the expression equal to zero? Solve the example below to help explain your answer to these questions. You are checking a solution for the rational expression and find that it makes one of the denominators in
(x - 2)/(x2+ 3x - 10) - x/(x + 5) = 4
Show how you get the answers {-3.8, 2}, yet only one of them is a true solution.
