Ashford 5: - Week 4 - Discussion 1

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 to complete this discussion: 

• 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 Inserting Math        Symbols 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.
