Expert Answer:

2x2 + 7x + 3

Let us try to split the middle term to get factors such that their sum is the middle term.

We get,

2x2 times 3 = 6x2

And,

Let two factors be 1x and 6x so that their sum is 7x (middle term) and their product is 6x2.

We will simplify now,

2x2 + 6x + x + 3

2x(x + 3) + 1(x + 3)

(2x + 1) (x + 3)
