Identify Common Factor: Look for a common factor in all terms.Check if there is a greatest common factor (GCF) that can be factored out from all terms of the polynomial 18m3−6m2−15m+5.The GCF of 18m3, 6m2, 15m, and 5 is 1, so there is no common factor to factor out from all terms.
Group Terms: Group terms to facilitate factoring by grouping.Group the first two terms together and the last two terms together: 18m3−6m2 + −15m+5.
Factor Out GCF: Factor out the GCF from each group.From the first group 18m3−6m2, factor out 6m2, and from the second group −15m+5, factor out −5.6m2(3m−1)−5(3m−1).
Factor Out Common Binomial: Factor out the common binomial factor.Now that we have a common binomial factor (3m−1), we can factor it out.(6m2−5)(3m−1).
