Question

Factor the GCF: 9x4y − 6x3y2 + 3x2y3.

Answer 1

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.
