Question 6 • Common Core Algebra I B-IC
The first two terms, 20x²y and 56x³, have a greatest common factor of 4x². The mystery term must also be divisible by 4x² without making the shared factor larger. The term 24x²y meets this condition: the coefficient GCF stays 4, and 56x³ has no y, so y is not part of the GCF. Thus, the mystery term could be 24x²y.
