Solve Rational And Radical Equations
Gbogbo ọrọ náà
Some equations hide the variable inside a fraction or under a square root. Solving them means clearing the fraction or removing the root to reach an equation you can already handle. But these moves come with a catch: they can introduce false solutions that do not actually fit the original equation.
In this lesson you will solve rational equations (with the variable in a denominator) and radical equations (with the variable under a root). The essential final step is to check every answer in the original equation and discard any extraneous solution, the false answer the algebra can create.
Ebumnobi
- Solve rational and radical equations in one variable and identify and discard any extraneous solutions.

- Solve sqrt(x + 1) = 3. A. x = 2 B. x = 4 C. x = 8 D. x = 10 Answer: C
- Solving sqrt(x) = x - 2 gives x = 1 and x = 4. Which is the valid solution? A. x = 1 only B. x = 4 only C. both D. neither Answer: B
- A solution that satisfies the squared equation but not the original is called: A. a double root B. an extraneous solution C. a complex root D. a discriminant Answer: B
- Why must answers to a radical equation be checked? A. Squaring can introduce false solutions B. The root is always negative C. Checking changes the answer D. It is never necessary Answer: A
