Problem $1$

Write an user defined function that determines the real roots of a quadratic equation $.$ Use the following structure for your function:$[]=$ quadraroots$($a$,$b$,$c$).$

To calculate the roots of the equation, the program calculates the discriminant D$,$ given by:

If D $>0$ the program displays $$The equation has two roots $\_\_\_\_\_$ and $\_\_\_\_\_$ and calculates them using

$$

If D $=0,$ the program displays $$The equation has one root $\_\_\_\_\_.,$ and calculate it using

If D $<0$ the program displays $$The equation has not real roots$$

$$

Call the program from the main file and obtain the results using the following equations:

a$.$

b$.$

c$.$
