Answer :
The complete factor of the expression [tex]\rm 3x (x +2) + 4 (x +2)[/tex] is [tex]\rm(x+2)(3x + 4)[/tex]. Then the correct option is A.
What is a factorization?
It is the method to separate the polynomial into parts and the parts will be in multiplication. And the value of the polynomial at this point will be zero.
The expression is [tex]\rm 3x (x +2) + 4 (x +2)[/tex].
To solve the expression properly we have to take common (x+2). Then we have
[tex]\rm 3x (x +2) + 4 (x +2)\\\\(x+2)(3x + 4)[/tex]
The correct factor is (x + 2)(3x + 4).
