Question 347566: Could you please help me solve 2y^3-11y^2+12y=0?
I'm completely blank and very tired and can't think anymore (had a volleyball game today after school and am trying to do loads of homework tonight).
Here's what I tried:
2(y.y.y)-11(y.y)+12y=0
2(y)-11+12y=0
-11+14y=0
+11 = +11
14y=11
___ ____
14 14
y=11/14
Thank you so much for your time and help.
