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,
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
