Revolt · Accepted Answer

No, the student is incorrect. While solving the equation algebraically results in the value -2, this value is an extraneous solution. If you substitute -2 back into the original equation, the denominators (a + 2) and (a^2 - 4) both become zero. Since division by zero is undefined, -2 cannot be a solution, and the equation actually has no solution.
