which one is correct:
factor completely:
y^4+3y^35y^215y
I ended up with two different ways but i am not sure which one is correct.
Is it
(A) y(y^25)(y+3)
or
(B) (y^35y)(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)(ysqrt5)(y+3)
