Answer:
No, the student is incorrect. When solving the equation, the algebraic solution found is a = –2. However, this value must be checked against the restrictions of the original equation. Substituting –2 into the denominators (a + 2) and (a^2 – 4) results in division by zero, which is undefined. Therefore, a = –2 is an extraneous solution, and the original rational equation actually has no solution.

Which of the following did you include in your answer?
A
No, the student did not check the solution to the derived equation in the original equation.B
No, a possible solution is a = –2, but it does not check in the original equation because it makes two of the denominators equal to zero.C
No, a = –2 is an extraneous solution, and there is no solution to the original rational equation.Did you find these answers helpful?
