Group Terms: Group the terms to find common factors.We can group the terms as follows: (6x3+12x2) and (−x−2).
Factor Common Factors: Factor out the greatest common factor from each group.From the first group 6x3+12x2, we can factor out 6x2, which gives us 6x2(x+2).From the second group −x−2, we can factor out −1, which gives us −1(x+2).
Write Factored Expression: Write the expression with the factored groups.Now we have 6x2(x+2)−1(x+2).
Factor Common Binomial: Factor out the common binomial factor.We can see that (x+2) is a common factor in both terms, so we factor it out to get (x+2)(6x2−1).
Check Quadratic Factorization: Check if the remaining quadratic can be factored further. The quadratic 6x2−1 is a difference of squares, which can be factored as (6x−1)(6x+1).
Write Final Form: Write the final factored form.The final factored form of the polynomial is (x+2)(6x−1)(6x+1).
