You can put this solution on YOUR website!
This is true since polynomials have integral exponents.

This polynomial is NOT in standard form though, you have to rearrange it to get k%28x%29+=+-5x%5E2%2B4x. But this is extra info that isn't directly related to what they are asking.

Let me know if you need more help or if you need me to explain a step in more detail.
