Answer:
[tex]\mathbf{3x}[/tex] is the greatest common factor for the expression: [tex]3x^2 -9x[/tex]
Step-by-step explanation:
We need to find the greatest common factor for the following expression: [tex]3x^2 -9x[/tex]
Greatest common factor is the number, that is divisible by both numbers. In the given expression 3x is the greatest number that is divisible by all the terms
[tex]3x^2 -9x\\3x(x-3)[/tex]
So, [tex]\mathbf{3x}[/tex] is the greatest common factor for the expression: [tex]3x^2 -9x[/tex]
