Factor the gcf: −6x4y5 − 15x3y2 + 9x2y3 (5 points)
−3x2y2(2x2y3 − 5x + 3y)
−3x2y2(2x2y3 + 5x − 3y)
3x2y2(2x2y3 + 5x − 3y)
−3(2x4y5 + 5x3y2 − 3x2y3)

*Hint: Before you try to factor anything, you try to see if they have a common factor.

Since -3 is a common factor, everything is divided by -3.

-6x^4y^5 - 15x^3y^2 + 9x^2y^3
-3(2x^4y^5 + 5x^3y^2 - 3x^2y^3)

Since you can still divide by x^2y^2, you do so.
-3x^2y^2 (2x^2y^3 + 5x - 3y)

The decimal expansion would be .27 repeated

The right answer is option d.
