Group Terms: Group the terms to find common factors.We can group the terms as follows: 3s3+s2 and −18s−6.
Factor Common Factors: Factor out the greatest common factor from each group.From the first group 3s3+s2, we can factor out s2, giving us s2(3s+1).From the second group −18s−6, we can factor out −6, giving us −6(3s+1).
Write Factored Form: Write the factored form of the polynomial.We found:3s3+s2=s2(3s+1)−18s−6=−6(3s+1)Now, we can factor out (3s+1) from both terms.So, the factored form of 3s3+s2−18s−6 is (s2−6)(3s+1).
