Im assuming its x^2+4x+3.....for x squared right.
First get the product of two numbers that equal to 3 (+3 * +1)
But also add up to 4 (+3 + +1)
so you apply them to your x^2 
(x+3)(x+1)

Answer:

(x+3)(x+1)

Step-by-step explanation:

In order to solve this you have to think in two numbers that multiplied by eachother will give as a result 3 and when added up will have as result 4.

Numbers:

6-.5

3-1

-3 -1

So we check our theories:

6*.5= 3  6+.5=6.5

3*1=3 3+1=4

-3*-1= 3 -3-1=-4

So the only option that is correct is 3 and 1, so our factors will be:

(x+3)(x+1)
