My Program is successful for 2 Test Cases. It fails Test Case 0.
Can i know what exactly is Test Case 0 checking, or is there some error in my code?

#2

for test case like 1 -11 28
you are printing roots like
4.0 7.0
instead of
4 7
correct that

#3
#4

I corrected that but it still fails test case 0

#5

@jayyp35,
When d>0, you should print “Real and Distinct” but you are printing “Real and Equal”

Sample test case:
Correct output:
Real and Distinct
4 7

Your output:
Real and Equal
4 7
