The factored form is (3x + 1)(x + 3)

Answer:

(3x+1)

Step-by-step explanation:

Given : [tex]3x^2 + 10x + 3[/tex]

To Find: Factors

Solution:

Now we will do middle term split

[tex]3x^2 + 10x + 3[/tex]

[tex]3x^2 + 9x+x+ 3[/tex]

[tex]3x(x+3)+(x+3)[/tex]

[tex](3x+1)(x+3)[/tex]

So, the factors are (3x+1) and (x+3)

So, Option A is true

Hence one of the factors of  [tex]3x^2 + 10x + 3[/tex] is (3x+1)
