Can anyone help?

I will give you a medal if you answer.

anonymous · Answer

a^2 (1+a+3 a^3)
So a = 0. and a = -0.53656516467

anonymous · Answer

No, just simlpify.  I don't need what a equals.
The top is simplified?

anonymous · Answer

@natalie135's factoring is correct, but don't set it equal to zero... the problem didn't have that in it.

anonymous · Answer

That could be simplified furthur to 
a^2 (1+a (1+3 a^2))

anonymous · Answer

I just need it simplified.

anonymous · Answer

I would have said your original statement was simplified.  But if you want it factored, I would go with @natalie135's first response.  The 2nd is ok, but it looks less simple, in my opinion :)
