Answer 1

Respuesta:

Explicación paso a paso:

$\texttt{La expresi\'on es:}\\\\36a^{4}-40a^{2}b^{2}+9b^{4}\\\texttt{Factorizando nos queda:}\\\\2a^{2}(18a^{2}-20b^{2})=36a^{4}-40a^{2}b^{2}\\-5b^{2}(8a^{2}-\frac{9}{5}b^{2})=-40a^{2}b^{2}+9b^{4}\\2a^{2}(18a^{2}-20b^{2})-5b^{2}(8a^{2}-\frac{9}{5}b^{2})$
