The polynomial 24x3 − 54x2 + 44x − 99 is factored by grouping. 24x3 − 54x2 + 44x − 9924x3 + 44x − 54x2 − 994x(____) − 9(____)What is the common factor that is missing from both sets of parentheses?

Regroup the terms as (24x³ + 44x) − (54x² + 99). Factoring each group gives 4x(6x² + 11) − 9(6x² + 11), so the common factor in both parentheses is 6x² + 11, choice C.
