Answer 1

$5)\frac{9}{16}x^{4}-\frac{16}{9}x^{2}=x^{2}(\frac{9}{16}x^{2}-\frac{16}{9})=x^{2}[(\frac{3}{4}x)^{2} -(\frac{4}{3})^{2}]=x^{2}(\frac{3}{4}x-\frac{4}{3})(\frac{3}{4}x+\frac{4}{3})\\\\\\6)3y^{5}-\frac{3}{25}y^{7}=3y^{5}(1-\frac{1}{25}y^{2})=3y^{5}[1^{2}-(\frac{1}{5}y)^{2}]=3y^{5}(1-\frac{1}{5}y)(1+\frac{1}{5}y)$
