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 3x3−5x2+12x−20.The terms do not share a common factor other than 1.
Group Terms: Group terms to facilitate factoring by grouping.Group the terms into two pairs: (3x3−5x2) and (12x−20).
Factor Out GCF: Factor out the GCF from each group.From the first group 3x3−5x2, factor out x2, which gives x2(3x−5).From the second group 12x−20, factor out 4, which gives 4(3x−5).
Write Factored Form: Write the factored form of the polynomial.Both groups now have a common factor of (3x−5).Factor out (3x−5) from x2(3x−5)+4(3x−5).The factored form is (3x−5)(x2+4).
