\(Q=\dfrac{\left[\left(x+3\right)\left(x+9\right)\right]\left[\left(x+5\right)\left(x+7\right)\right]+2014}{\left(x^2+12x+32\right)}\)
\(Q=\dfrac{\left(x^2+12x+27\right)\left(x^2+12x+35\right)+2014}{\left(x^2+12x+32\right)}\)
\(Q=\dfrac{\left(t-5\right)\left(t+3\right)+2014}{t}\)
\(Q=\dfrac{\left(t^2-2t-15\right)+2014}{t}=t-2+\dfrac{1999}{t}\)
