**Reiny**, Thursday, February 2, 2012 at 8:49pmto have imaginary roots

b^2 - 4ac < 0

b^2 - 4(1)(5) <0

b^ < 20

± b < √20

b < √20 AND b > -√20

so -√20 < b < √20

It would be that number "just to the right" of -√20

but of course we cannot name that number.

If you think you have found it, I can find a number which is closer to it.

Poorly worded question!
