Let's analyze the given equation.
We are asked to check if either
are . An extraneous solution is a solution that emerges from the process of solving the problem, but is not a valid solution of the equation. First, let's check if
is a solution by substituting it into the equation.
Since the substitution of
produces a true statement, the solution
is a valid one. Next, Let's check
Notice that in this case we get that the denominator is
which is impossible. Therefore,
is not a valid solution, so it is an extraneous solution.
