- can a polynomial have an irrational cooeficient?

- Relevant Equations
- is this is poloynomial? y = x^2 + sqrt(5)x + 1

Is this a polynomial? y = x^2 + sqrt(5)x + 1

I was told NO, the coefficients had to be rational numbers. I this true?

It seem to me this is an OK polynomial.

I can graph it and use the quad formula to find the roots? so why or why not?
