Answer 2

x 3 − 3 x 2 + 5 x − 15

Group the first two terms and the last two.

( x 3 − 3 x 2 ) + 5 x − 15

Factor the greatest common denominator (GCF) of each group.

x 2 ( x − 3 ) + 5 ( x − 3 )

Factor the polynomial by factoring out the greatest common denominator, x - 3  

.

( x − 3 ) ( x 2 + 5 )
