ANSWER:
[tex]\begin{gathered} 3x^2\cdot(x^2+2x+3) \\ 4\cdot(x^2+3x-2) \end{gathered}[/tex]
STEP-BY-STEP EXPLANATION:
We have the following polynomial
A.
[tex]3x^4+6x^3+9x^2[/tex]
We can calculate the GCF by means of the common factor, like this
[tex]3x^2\cdot(x^2+2x+3)[/tex]
B.
[tex]4x^2+12x-8[/tex]
We can calculate the GCF by means of the common factor, like this
[tex]4\cdot(x^2+3x-2)[/tex]
