2.

FLASHCARD QUESTION

Front

What is the first step in solving a rational equation?

Back

The first step is to identify any restrictions on the variable that would make the denominator zero, as these values are excluded from the solution.

3.

FLASHCARD QUESTION

Front

How do you find the least common denominator (LCD) in a rational equation?

Back

The least common denominator is found by determining the least common multiple of the denominators of all the rational expressions in the equation.

4.

FLASHCARD QUESTION

Front

What is an extraneous solution?

Back

An extraneous solution is a solution that emerges from the process of solving the equation but does not satisfy the original equation.

5.

FLASHCARD QUESTION

Front

How do you check for extraneous solutions in rational equations?

Back

To check for extraneous solutions, substitute the solution back into the original equation to see if it holds true.

6.

FLASHCARD QUESTION

Front

What are excluded values in rational equations?

Back

Excluded values are the values of the variable that make any denominator in the equation equal to zero, which cannot be included in the solution set.

7.

FLASHCARD QUESTION
