For this case we have the following expression:
[tex] 9x^4y - 6x^3y^2 + 3x^2y^3
[/tex]
For this case what you should do is observe the terms that are repeated in the given expression.
We have then:
[tex] 3x^2y
[/tex]
It is the term that is present in the whole expression.
Therefore, by doing common factor we have:
[tex] 3x^2y (3x^2 - 2xy + y^2)
[/tex]
Answer:
the GCF is:
[tex] 3x^2y (3x^2 - 2xy + y^2) [/tex]
option A: a 3 is missing at the beginning of the option.
