The way you tried to write out this equation makes it difficult to understand. If you mean this:

$<br /> \frac { x^2 + 6x + 8} {x^2 + 8x + 16}<br />$

then you can factor both the numerator and denominator, and simplify from there. Non-permissible values are any values for x that make the denominator = 0.
