y\left(9x^{4}-16y^{4}\right)
Factor out y.
\left(3x^{2}-4y^{2}\right)\left(3x^{2}+4y^{2}\right)
Consider 9x^{4}-16y^{4}. Rewrite 9x^{4}-16y^{4} as \left(3x^{2}\right)^{2}-\left(4y^{2}\right)^{2}. The difference of squares can be factored using the rule: a^{2}-b^{2}=\left(a-b\right)\left(a+b\right).
y\left(3x^{2}-4y^{2}\right)\left(3x^{2}+4y^{2}\right)
Rewrite the complete factored expression.
