(2x + 4) ( x +1 ) are factors .
Step-by-step explanation:
Given : 2x² + 9x + 4.
To find : Factor.
Solution : We have given that 2x² + 9x + 4.
On factoring 2x² + 8x + 1x + 4.
Taking common 2x from first two terms and 1 from last two terms .
2x ( x +4 ) +1 (x +4 ).
On grouping
(2x + 4) ( x +1 ).
Therefore , (2x + 4) ( x +1 ) are factors .
