Given:


(2x^2+x-21)/(x^2+2x)*(8x+16)/(x-3)

To find: The reduced form

Step-by-step explanation:

Let us write it as the factored form.


\begin{gathered} (2x^2+x-21)/(x^2+2x)*(8x+16)/(x-3)=\frac{2x^2+7x-6x-21}{x(x^{}+2)}*(8(x+2))/(x-3) \\ =\frac{x(2x^{}+7)-3(2x+7)}{x(x^{}+2)}*(8(x+2))/(x-3) \\ =\frac{(x-3)(2x+7)}{x(x^{}+2)}*(8(x+2))/(x-3) \end{gathered}

Simplifying we get,


(8(2x+7))/(x)

Final answer: The simplest form is,


(8(2x+7))/(x)
