Answer:

(x+1)(3x+2)

Explanation:

Let's use the "x" method:

Two numbers multiplied is equivalent to 6 and their sum is 5.

The numbers would be 3 and 2. Now let's split up 5x into 3x and 2x:

3x²+3x+2x+2

Then we factor:

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

We can combine 3x and 2 since they are both being multiplied by x+1

(x+1)(3x+2)
