2\left(x^{2}y+4xy+4y\right)
Factor out 2.
y\left(x^{2}+4x+4\right)
Consider x^{2}y+4xy+4y. Factor out y.
\left(x+2\right)^{2}
Consider x^{2}+4x+4. Use the perfect square formula, a^{2}+2ab+b^{2}=\left(a+b\right)^{2}, where a=x and b=2.
2y\left(x+2\right)^{2}
Rewrite the complete factored expression.
