Group Terms for Factoring: Group terms that can be factored by grouping.Group the first two terms and the last two terms separately.10n3+10n2−3n−3 can be grouped as (10n3+10n2)+(−3n−3).
Factor Out Common Factors: Factor out the greatest common factor from each group.From the first group 10n3+10n2, factor out 10n2.10n3+10n2=10n2(n+1).From the second group −3n−3, factor out −3.−3n−3=−3(n+1).
Write Factored Expression: Write the expression with the factored groups.The expression now looks like this: 10n2(n+1)−3(n+1).
Factor Out Common Binomial: Factor out the common binomial factor.Both terms have a common factor of (n+1).Factor out (n+1) from both terms.The factored form is (n+1)(10n2−3).
