what is the completely factored form of x4y – 4x2y – 5y?
y(x2 – 5)(x2 1)
y(x2 5)(x2 – 1)
(x2y – 5)(x2 1)
(x2y 5)(x2 – 1)

If you would like to write x^4y - 4x^2y - 5y in a completely factored form, you can do this using the following steps:
x^4y - 4x^2y - 5y = y * (x^4 - 4x^2 - 5) = y * (x^2 + 1) * (x^2 - 5)
The correct result would be y * (x^2 + 1) * (x^2 - 5).
