Answer:
( 3x² + 5 ) ( x + 2 )
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
