Bhaskara’s Formula

Adapted by Neilor Tonin, URI Brazil | Timelimit: 1

Read 3 floating-point numbers. After, print the roots of bhaskara’s formula. If it’s impossible to calculate the roots because a division by zero or a square root of a negative number, presents the message “Impossivel calcular”.

Input

Read 3 floating-point numbers A, B and C.

Output

Print the result with 5 digits after the decimal point or the message if it is impossible to calculate.
