Answer:
1. To clear the rational equation [tex] \frac{1}{a} + \frac{4}{b} = 6[/tex], we multiply both sides of the equation by ab.
2. To solve the rational inequality, we rewrite one side equal to zero (0) the inequality.
3. To clear a rational equation, we multiply both sides of the equation by the Least Common Denominator (LCD) of the rational equation.
4. Construct a sign line to determine the sign of the function of each interval for rational inequality.
5. An extraneous solution is an apparent solution that does not solve its equation.
