The multiple zero is x = -4.
The multiplicity is 2 because there are two values of x.
Answer:
(x + 5) (x^2 -3)
Step-by-step explanation:

Do the grouping:

Then factor out
in the first and −3 in the second group.

Factor out the common term x + 5 by using the distributive property.
Polynomial
is not factored in since it does not have any rational roots, thus getting the following:
