Quadratic Equation Solver
A quadratic equation is a polynomial equation of the 2nd degree. It's basic form is this:
ax2 + bx + c = (x - x1)(x - x2)
And the solutions are calculated:
|− b ± √ b2 - 4ac |
| 2a |

There are few more things you should know.
The expression under the square root is called the discriminant:
D = b2 - 4ac
There are 3 possible cases:
- If D > 0, both roots are real numbers.
- If D = 0, then there is exactly one root, aka called a double root
- If D < 0, (non-real) complex conjugates roots
