When factoring a polynomial, why is it important to first factor out the GCF?

• It simplifies the polynomial, making further factoring steps easier.

• It is a requirement for the polynomial to be considered factored completely.

• It increases the degree of the polynomial.

• It changes the signs of the polynomial's terms.
