What multiples into 4 and adds up to 5

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)
