Question 121043: Give an example (other than the ones in the lecture or the text book) of a rational equation where the solution(s) makes the denominator equal to zero, and hence must be rejected; i.e the solutions are extraneous solutions.
You can put this solution on YOUR website! Sometimes with rational equations a results in a . This solution since division by zero is .
If a denominator is comprised of a variable or a variable expression, consider the value or values that would make the denominator equal to zero and make a note excluding those values as solutions.
Example:
Solve the rational equation algebraically ….note that a denominator is comprised of a variable and …….for denominators of ,, and , the is , so we will have:
