You are given A,B,C of a quadratic equation you have to find its roots.
We just take input and use SridharAcharya Rule.
We take input using scanner or bufferedreader. then we calculate sqrt(b^2-4ac) if its negative we print “No Roots” else we then do (-b+d)/2a and print it. and which is the positive root. we then print (-b-d)/2a which is negative root.
