I was thinking it was two different rational solutions but I'm not completely sure.

Answer 1

if the roots are equal
\[b^2-4ac=0\]

Answer 2

if the there exist no real solution then
\[b^2-4ac<0\]

Answer 3

or >0 for two different rational solution

Answer 4

according to ur question u must say equal to zero, hope this helps

Answer 5

this is the answer Two identical rational solutions

Answer 6
