Group Terms: Group the terms to find common factors.We can group the terms as follows: (10g3+10g2) and (−7g−7).
Factor Common Factors: Factor out the greatest common factor from each group.From the first group 10g3+10g2, we can factor out 10g2, which gives us 10g2(g+1).From the second group −7g−7, we can factor out −7, which gives us −7(g+1).
Write Factored Expression: Write the expression with the factored groups.Now we have 10g2(g+1)−7(g+1).
Factor Common Binomial: Factor out the common binomial factor.We can see that (g+1) is common in both terms, so we factor it out to get (g+1)(10g2−7).
