Answer:

\frac{1}{4x^2\left(x+1\right)}

Step-by-step explanation:

\frac{2x-16}{8x^3+56x^2}\cdot \frac{x+7}{x^2-7x-8}

You first factor things out.

\frac{x-8}{4x^2\left(x+7\right)}\cdot \frac{x+7}{x^2-7x-8}

You then multiply. (Cancel common factor, X+7)

\frac{x-8}{4x^2\left(x^2-7x-8\right)}

You factor again.

\frac{x-8}{4x^2\left(x+1\right)\left(x-8\right)}

Then cancel out common fact x-8.

So therefore, you get the final answer,

\frac{1}{4x^2\left(x+1\right)}
