There are two vertical asymptotes at x = 2 and x = -2.
It looks like you missed a division sign in your problem to create a fraction that would have asymptotes.
The denominator would factor to (x + 2)(x - 2). Since we can't have zero in the denominator, we will have an asymptote at 2 and -2. This is because those values would make the denominator zero.
