We are given the trinomial
![x^2+3x+2](https://img.qammunity.org/2023/formulas/mathematics/high-school/y2w6mea2ve3jqjd4d6ixxae8yaze0lok9t.png)
We can factor it as the product two binomials as
![(x+a)(x+b)](https://img.qammunity.org/2023/formulas/mathematics/college/v5ba5bezpeduntqotbr37dxvqtnuie0rex.png)
Where
a and b are two numbers that has
• a product of 2
,
• a sum of 3
So, which two numbers multiplied gives us "2" and added gives us "3"?
It is "+2" and "+1".
Thus, we can factor the trinomial as:
![\begin{gathered} x^2+3x+2 \\ =(x+2)(x+1) \end{gathered}](https://img.qammunity.org/2023/formulas/mathematics/college/fa8gcqcpl2dprwo1cmo8qakh1o6403v0gb.png)
