Answer:

Step-by-step explanation:

Multiply and combine like terms.

Consider
as a polynomial over variable x.

Find one factor of the form kx^m
+n, where kx^m divides the monomial with the highest power 3x^3 and n divides the constant factor −y^3
. One such factor is 3x−y. Factor the polynomial by dividing it by this factor.

Consider
. Use the perfect square formula,
=
, where a=x and b=y.

Rewrite the complete factored expression.
