3X
I take this to be 3x3 - 21x2 + 36x. I notice that 3x is a factor common to all three terms. Let me remove that first. 3x ( x2 - 7x + 12 ) "By inspection" I can make up the two factors in the parenthesised part. 3x ( x - 4 ) ( x - 3 )
The GCF is 3x.
Since 3x is a factor of 3x^2, it is automatically the GCF.
The GCF is 3x
The GCF of 6x and 9x is 3x
