Discriminant - Wikipedia, the free encyclopedia

If the discriminant is positive the polynomial will have 17 distinct real roots.

If the discriminant is equal to zero, the polynomial will have repeated roots and therefore less than 17 distinct real roots. But there's no way of knowing how many distinct real roots there are.

If the discriminant is less than zero, ..... I leave this case for you to research. - Jul 28th 2009, 05:39 AMfuaada
Thanks for the good reply....the informations are really helpful for me to go on with my research....
