Determine the maximum of zeros of the polynomial function:  -9x^2+2x+2 ?

anonymous · Answer

Before I give any hints, what do you think it could be?  Is there away to at least find some roots for this?

anonymous · Answer

I think it can be either 3 or 4 ?

anonymous · Answer

Why would you say that?
Also, do you know about the Quadratic formula?

anonymous · Answer

Look do you know the answer because im really running out of time ..

anonymous · Answer

I do, but I will not (nor will anyone else) just give you the answer.  I'm here to try and help you understand how to get it.

anonymous · Answer

I understand that. But I think I have the answer , its 2.

anonymous · Answer

Yes that is correct.   All polynomials have as many roots that correspond to the highest degree in the polynomial.
