    Answer:

    ( 3x² + 5 ) ( x + 2 )

    Step-by-step explanation:

    3x³ + 6x² + 5x + 10

    → Factor 3x³ + 6x² by taking out the LCM of the number

    3x² ( x + 2 )

    → Factor 5x + 10 by taking out the LCM of the number

    5 ( x + 2 )

    → Combine the 2 brackets together

    ( 3x² + 5 ) ( x + 2 )

    → Expand to check its the right answer, if you get 3x³ + 6x² + 5x + 10 then it is correct

    ( 3x² + 5 ) ( x + 2 ) = 3x³ + 6x² + 5x + 10
