Since all of these numbers are relatively close to 500, we can do 500*6 to get 3000.

$\dfrac{ \dfrac{x+3}{4x^2-16} }{ \dfrac{2x^2+10x+12}{2x-4} }$

-----------------------------------------------------------------------------------
Write the divide fraction horizontally:
-----------------------------------------------------------------------------------

$= \dfrac{x+3}{4x^2-16} \div \dfrac{2x^2+10x+12}{2x-4}$

-----------------------------------------------------------------------------------
Factorise the numerators and denominators when possible:
-----------------------------------------------------------------------------------

$= \dfrac{x+3}{4(x+2)(x-2)} \div \dfrac{ 2(x + 3) (x + 2)}{2(x-2)}$

-----------------------------------------------------------------------------------
Convert the divide fraction to multiplication fraction
-----------------------------------------------------------------------------------

$= \dfrac{x+3}{4(x+2)(x-2)} \times \dfrac{2(x-2)}{2(x+3)(x+2)}$

-----------------------------------------------------------------------------------
Cancel the factors
-----------------------------------------------------------------------------------
$= \dfrac{1}{4(x+2)} \times \dfrac{1}{(x+2)}$

-----------------------------------------------------------------------------------
Combine to single fraction
-----------------------------------------------------------------------------------

$= \dfrac{1}{4(x+2)^2}$
