Omar grouped the terms and factored the GCF out of the groups of the polynomial 3x3 – 15x2 – 4x + 20. His work is shown. Step 1: (3x3 – 15x2) + (–4x + 20) Step 2: 3x2(x – 5) + 4(–x + 5) Omar noticed that he does not have a common factor. Which accurately describes what Omar should do next? A: Omar should realize that his work shows that the polynomial is prime. B: Omar should go back and regroup the terms in Step 1 as (3x3 – 15x2) – (4x + 20). C: In Step 2, Omar should factor only out of the first expression. D: Omar should factor out a negative from one of the groups so the binomials will be the same.
