Answer:
Step-by-step explanation:
In order to find the values to factorize the equation, we need to find the factors the factors of 3 that sum to 4
The factors of 3 are [tex]\pm: 1, 3[/tex]
We can make 4 with 1 + 3
Since all the values are positive, both of the factors will have addition
[tex]x^2+4x+3\\(x+3)(x+1)\\\\x^2 + x + 3x + 3\\x^ + 4x + 3[/tex]
