# algebra 2..again

posted by gq

2y^3-10y^2+12y...need to factor again..i got to the second step...
2y(y^2-5y+6)...think that's right but i don't get how to factor that out..help plz..

1. drwls

Go for one more factoring step and you get
2 y (y-2)(y-3)

2. Jason

Try it this way...

2y^3 - 10y^2 + 12y

Switch A&C to make it easier (always acceptable, just remember to keep your signs):
12y - 10y^2 + 2y^3

Factor out a GCF, in this case it's 2y:
2y(6 - 5y + y^2)

Next, factor a trinomial:
2y(2 - 1y)(3 - 1y)

Hope this helps you!
