Equation Solver

A program that solves a quadratic equation and finds an extremum of the parabola.

Example:

$ equation_solver 1 -2 -3 -3 4 5 0 4 -4

Output:
(1 -2 -3) => (-1, 3) Xmin=1
(-3 4 5) => (-0.7863, 2.11963) Xmax=0.666667
(0 4 -4) => (1) no relative extreme

Details

• parameters trey is a set of quadratic coefficients, i.e. a, b, c
• coefficients are integers (without a fractional component)
• protection against input garbage, i.e. 4 aaa 11
• multithreading for calculation of each equation concurrently

How to use

Build:

mkdir build && cd build

cmake ../src
cmake --build .

Run:

• try this:

./equation_solver 1 -2 -3 -3 4 5 0 4 -4 3 4 5 0 0 0 4 aaa 11

• or run with your equations
