MAT 222

THE THIRD LETTER OF MY LAST NAME IS N

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.

• If the third  letter of your last  name is	On page 636, solve the following problem by factoring	Solve the following problem by using the Quadratic Formula
  A or L	46	48 on p. 646
  B or K	88	46 on p. 646
  C or J	84	44 on p. 646
  D or I	10	20 on p. 646
  E or H	8	18 on p. 646
  F or G	6	16 on p. 646
  M or Z	38	48 on p. 636
  N or Y	40	50 on p. 636
  O or X	42	52 on p. 636
  P or W	44	54 on p. 636
  Q or V	80	56 on p. 637
  R or U	2	78 on p. 637
  S or T	4	82 on p. 637

• 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.
