Answer

Factor by grouping Explanation 1. Identify the polynomial structure The polynomial \( 3x^3 + 5x + 6x^2 + 10 \) has four terms, suggesting factor by grouping might be suitable. 2. Apply factor by grouping Group terms: \( (3x^3 + 6x^2) + (5x + 10) \). 3. Factor each group First group: \( 3x^2(x + 2) \). Second group: ( 5(x + 2) ). 4. Combine common factors Common factor is ( (x + 2) ), so the expression becomes \( (3x^2 + 5)(x + 2) \).
