Let's solve the quadratic equation by examining its roots. The given quadratic equation is:

[tex]\[ y = -2x^2 - 8x - 8 \][/tex]

To find the roots, we need to determine the values of [tex]\( x \)[/tex] for which [tex]\( y = 0 \)[/tex]. Essentially, we're solving:

[tex]\[ -2x^2 - 8x - 8 = 0 \][/tex]

After thorough analysis, we find that the solution to this quadratic equation yields one real solution:

[tex]\[ x = -2 \][/tex]

So, the correct answer from the given options is:

[tex]\[ -2 \][/tex]
