Objective:

This activity has the purpose for helping students to explain how to design modules and functions in terms of cohesion and coupling $($Objective $2).$

Student Instructions

Via the Blackboard Discussion Board titled Cuadratic Formular, complete the following

This activity has a total of $10$ points.

For due date refer to the course Calendar in the Tools area of Blackboard.

You must create your thread $(1)$ and make at least two $(2)$ comments on your classmates with any of the following:

Share your initial comment and compare it with that of your classmate

Make a question to verify or find more information

Share your initial comment and compare it with that of your classmate

Offer suggestions to your classmate

Complete or complement the comment of your classmate

Remember to support your answers and comments with specific and appropriate references from the content studied.

Complete:

$1.$ Create a function to solve the Quadratic Formula as know as

Click for more options

The function must have only $3$ reference parameters which are the coefficient of the quadratic equation a$,$ b and c $,$ at the end the function must return the real value of x$.$ If a$=0,$ or there is a negative root square obtained, the function must sent a message error to the user $$ The coefficient of it can$$t be equal zero$$ or $$Negative root solution are Founded Sorry try again$.$

$2.$ For this problem you need to use the following algorithms tools already learned on previous modules such as PAC, IPO, flow charts, and the new technic learned on this module such as Coupling interactivity chart diagram, Data Dictionary. Test your result using the following data let a$=1$ b$=2$ c$=1,$ let a$=4,$b$=3,$ c$=1,$ and let a$=0$ b$=3,$c$=2.$
