solve a*x^2+b*x+c=0 in matlab

To solve a quadratic equation of the form a*x^2 + b*x + c = 0 in MATLAB, you can use the built-in roots function. Here's the step-by-step process:

1. Define variables a, b, and c with appropriate values.
2. Use the roots function to calculate the roots of the quadratic equation.

Here's an example MATLAB code:

main.m
% Step 1: Define the variables
a = 1;
b = -5;
c = 6;

% Step 2: Calculate the roots
roots_of_equation = roots([a, b, c]);

8 lines

The output roots_of_equation will be a vector containing the roots of the quadratic equation.

Note: If the quadratic equation has complex roots, the roots function will return complex numbers.
