Group Terms: Group terms to find common factors.Group the first two terms and the last two terms separately.(2t3+t2)+(−20t−10)
Factor Common Factors: Factor out the greatest common factor from each group.From the first group, factor out t2.t2(2t+1)From the second group, factor out −10.−10(t+1)
Rewrite Expression: Rewrite the expression with the factored groups. t2(2t+1)−10(t+1)
Find Common Binomial Factor: Look for a common binomial factor.Notice that there is no common binomial factor between (2t+1) and (t+1), so the expression cannot be factored further.
