how can i solve this function

The classic quadratic formula says that the two roots of the quadratic equation ax2+bx+c=0 are x1,x2=(-b±√(b2-4ac). Write a function that keep solutions x1,x2 and use this function in another script file. It takes as integers to input the values ​​of a, b, and c and solve the equation using the first function you define in step one. Finally, use this to solve the equation 8x2+4x-2=0.

You can use roots() to find the solutions. Then simply put roots() into a function and call it in a script.
a = 3;
b = ..........
[x1, .....] = SolveQuadratic(a, b, ....................
% SolveQuadratic is a function you write that calls roots inside it and returns the two roots.
etc.
