(MATLAB) Write a function called eig two by two which takes as parameter a 22 matrix A and returns its eigenvalues. You want to use the function that you wrote in part a and the quadratic expression in part b.

Function from part a:

function [x1, x2] = quadratic_solver(a,b,c)

x1 = ((-b) + (sqrt(b ^ 2 - 4 * a * c))) / (2 * a);

x2 = ((-b) - (sqrt(b ^ 2 - 4 * a * c)))/ (2 * a);

disp x1

disp x2

end

quadratic expression from part b:

^2 - (a+d) + (a*d-b*c)
