现给出一元二次方程一般形式中a,b,c的值，求方程的解(保证方程有两个不相等的实数根，-1000<=a,b,c<=1000)。\ 第一行输出较大的根，第二行输出较小的根。

题目描述

The Department of economic development of IT City created a model of city development till year 2100. To prepare report about growth perspectives it is required to get growth estimates from the model. To get the growth estimates it is required to solve a quadratic equation. Since the Department of economic development of IT City creates realistic models only, that quadratic equation has a solution, moreover there are exactly two different real roots. The greater of these roots corresponds to the optimistic scenario, the smaller one corresponds to the pessimistic one. Help to get these estimates, first the optimistic, then the pessimistic one.
