Methodology Justification in Structural Modeling

A structural engineer is simplifying a stress-analysis formula: xy+8y+3x+24xy + 8y + 3x + 24. Before applying the factoring by grouping method, the engineer confirms that a single greatest common factor (GCF) cannot be pulled from the entire expression. Based on the characteristics of this specific polynomial, why is it impossible to factor out a single GCF from all four terms at once?
