Ashford 5: - Week 4 - Discussion 1

 

Your initial discussion thread is due on Day 3 (Thursday) and you have until Day 7 (Monday) to respond to your classmates. Your grade will reflect both the quality of your initial post and the depth of your responses. Reference the Discussion Forum Grading Rubric for guidance on how your discussion will be evaluated.

 

     

Solving   Quadratic Equations

In this discussion, you will solve quadratic equations by two main methods: factoring and using the quadratic formula. Read the following instructions in order and view the example (available for download in your online classroom) to complete this discussion. Please find the problems assigned to you in the table below:

• For the factoring problem, be sure you show all steps      to the factoring and solving. Show a check of your solutions back into the      original equation. 
• For the quadratic formula problem, be sure that you use      readable notation while you are working the computational steps. Refer to      the Inserting Math Symbols handout for guidance with formatting.
• Present your final solutions as decimal approximations      carried out to the third decimal place. Due to the nature of these      solutions, no check is required. 
• Incorporate the following four math vocabulary words      into your discussion. Use bold font to emphasize the words in your      writing. Do not write definitions for the words; use them appropriately in      sentences describing your math work.
  • Quadratic formula
  • Factoring
  • Completing the square
  • Discriminant

Your initial post should be at least 250 words in length. Support your claims with examples from required material(s) and/or other scholarly resources, and properly cite any references. Respond to at least two of your classmates’ posts by Day 7.

Carefully review the Grading Rubric for the criteria that will be used to evaluate your discussion.
