Can you present the problem a little less ambiguously?

anonymous · Answer

that is how it is presented to me.....that is all I know

lgbasallote · Answer

your question is EXACTLY like the one i wrote?

anonymous · Answer

yes

lgbasallote · Answer

oh. i think i got it. you're supposed to substitute x = -5
$$\implies \frac{8}{(-5)^2 - 6(-5) +5} \implies \frac{8}{25 - (-30) + 5} \implies \frac{8}{25 + 30 + 5} \implies \frac{8}{60} \implies \frac{2}{15}$$
got it now?
