\large\textbf{Given} :

(x^{2} -8x+12)(x^{2} -16)\div (x^{2} - 36)(x^{2} -4)

\large\textbf{Identity Applied }:

(a^{2} - b^{2} )= (a+b)(a-b)

\large\textbf{Solution }:

\mathsf{\implies \frac{(x^{2}-8x+12) (x^{2} -36 )}{(x^{2} -36)(x^{2} -4)}}

\mathsf{\implies \frac{(x^{2}-2x-6x+12 )(x^{2} -4)}{(x^{2} -36)(x^{2}-4 )}}

\mathsf{\implies \frac{x(x-2)-6(x-2)(x^{2} -16)}{(x^{2}-36 )(x^{2}-4)}}

\mathsf{\implies \frac{(x-6)(x-2)(x^{2} -4^{2}) }{(x^2-6^2)(x^2-2^2)}}

\mathsf{\implies \frac{(x-6)(x-2)(x-4)(x+4)}{(x+6)(x-6)(x+2)(x-2)}}

\color{deeppink}{\because (a^2-b^2)=(a+b)(a-b)}

\mathsf{\implies \frac{(x-4)(x+4)}{(x+6)(x+2)}}
