Write a Python code consisting of a function $($call it quadroots$)$ that calculates the

roots of the quadratic equation using the expressions given by $(3).$ Show that your code

works for a few values of a$,$ b$,$ c$.$

However, in some cases, the roots when computed by equation $(3)$ can lead to round$-$off

errors. To see this, consider the case when b $>0$ and b$2>>4$ac$.$ In this case, the two

terms in the numerator in the expression for x$1$ are close to each other and the numerator

may suffer from round$-$off errors. A similar situation arises in the expression for x$2$ when

b $<0.$
