PLEASE HELP!!! We are using the discriminant to find how many solutions there are in the quadratic equation. I understand that if it's >0 then 2 real solutions, =0 then 1 real solution, and <0 no real solutions. Why when a discriminant is negative there are two solutions but other times 0? Please​ explain how can you tell.

If there is a negative discriminant, there won't be any real solutions. This is because two values can't be squared to give a negative value. This would mean there are no x - intercepts and also, no solutions.

Hope This Helps You!

Good Luck (:

Have A Great Day ^-^
