Question

Factor the GCF: 9x4y − 6x3y2 + 3x2y3.

a. x2y(3x2 − 2xy + y2)
b.3xy(3x2 − 2xy + y2)
c.3xy2(3x2 − 2xy + y2)
d.3x2y(3x2 + 2xy + y2)

Answer 1

option A

Explanation:

Answer 2

For this case we have the following expression:

`9x^4y - 6x^3y^2 + 3x^2y^3`
For this case what you should do is observe the terms that are repeated in the given expression.
We have then:

`3x^2y`
It is the term that is present in the whole expression.
Therefore, by doing common factor we have:

`3x^2y (3x^2 - 2xy + y^2)`
Answer:
the GCF is:

`3x^2y (3x^2 - 2xy + y^2)`
option A: a 3 is missing at the beginning of the option.
