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)
