# Quadratic equations

Quadratic equations are interesting in that the function can cross the

`OX`

axis twice, once, or even never.You are asked to find the points where the quadratic function crosses the

`OX`

axis. To recap, that calculation can be done through the following procedure:Given

`a`

, `b`

, and `c`

integers, print the points of the solutions on separate lines (the points at which the graph crosses `OX`

axis), and in case there are no such points, the program should print `No solutions`
