Question: ( using Matlab ) Write a function x = realRoots ( a , b , c ) which outputs real roots of the quadratic equation

(using Matlab) Write a function x = realRoots(a,b,c) which outputs real roots of the quadratic equation
a x2+bx +c=0. If there are no real roots, then the output is x =[]. Demonstrate the
performance of your function on three examples of your choice which generate two,
one, and no real roots.
