Answer:

Step-by-step explanation:
The given polynomial has zeros at:
x=−3, x=−1, and x=1.
This means that:
x+3, x+1, and x-1 are all factors of this polynomial.
The factored form of this polynomial is :

We expand the last two factors using difference of two squares.




This is the standard form because it is now in decreasing powers of x.
