Answer:

(2x+1) (x+2)

Step-by-step explanation:

2x^2 +5x+2

(2x +   )   (x+   )

We need to determine what goes in the empty spots

2 factors into 2 and 1  so we have two options

(2x +   )   (x+   )  the first spot can be either 2 or 1  and the second spot can be the other

We need to get to 5  so I will put the 2 where it will multiply by the 2x

(2x+1) (x+2)

Check

FOIL

2x^2 +4x +x+2

2x^2 +5x+2
