Homework Help: math,algebra,correction

Posted by jacky20 on Wednesday, April 18, 2007 at 9:30pm.

which one is correct:

factor completely:

y^4+3y^3-5y^2-15y


I ended up with two different ways but i am not sure which one is correct.

Is it

(A) y(y^2-5)(y+3)

or
(B) (y^3-5y)(y+3)

Personally i think its A but then when i do foil to both of them i get the same answer.

Both are the same, but neither is factored completely.

y(y+sqrt5)(y-sqrt5)(y+3)
