Group Terms: Group the terms to find common factors.We can group the terms as follows: (9g3+9g2) and (−10g−10).
Factor Common Factors: Factor out the greatest common factor from each group.From the first group 9g3+9g2, we can factor out 9g2, which gives us 9g2(g+1).From the second group −10g−10, we can factor out −10, which gives us −10(g+1).
Write Factored Expression: Write the expression with the factored groups.Now we have 9g2(g+1)−10(g+1).
Factor Common Binomial: Factor out the common binomial factor.We notice that (g+1) is a common factor in both terms, so we factor it out to get (g+1)(9g2−10).
Check Quadratic Factor: Check if the quadratic factor can be factored further.The quadratic factor 9g2−10 does not factor nicely with integer coefficients, so it is already in its simplest form.
