Nine degrees OJ topic 1103: Two-time equation calculator

Title Description:

Design a two-time equation calculator

Input:

Each case is a two-time equation of expression for x, and for simplicity, each coefficient is an integer form.

Output:

Each case outputs two real numbers (from small to large output, separated by spaces), retains two decimal places, and outputs "no solution" if no solution is provided.

Sample input:

X^2+x=3x+4

Sample output:

-1.24 3.24
