Answer:

3a

Step-by-step explanation:

12a and 9a^2

first find the GCL between 9 and 12 which is 3

then find the GCL between a and a^2 which is a

combine them to form 3a

The greatest common factor of 12a and [tex]9a^2[/tex] is 3a.

Given that,

  • There is 12 a and [tex]9a^2[/tex]

calculation:

The GCF should be

12a = [tex]3 \times 4a[/tex]

And, [tex]9a^2 = 3\times 3a[/tex]

based on this, the factor should be 3a
