2 algebra problems with definitions

A SAMPLE IS ATTACHED BUT THE SAMPLE QUESTIONS ARE BASED ON DIFFERENT NUMBERS OF COURSE

Use FACTORING to solve:

x² + 3x – 18 = 0

Use the QUADRATIC FORMULA to solve:

(a – 2) ^ 2 = 8

• For the factoring problem, be sure you show all steps to thefactoring and solving. Show a check of your solutions back into theoriginal equation.

• For the quadratic formula problem, be sure that you use readablenotation while you are working the computational steps. Refer to theInserting Math Symbols handout for guidance with formatting.

• Present your final solutions as decimal approximations carried outto the third decimal place. Due to the nature of these solutions, nocheck is required.

• Incorporate the following four math vocabulary words into your discussion. Use boldfont to emphasize the words in your writing. Do not write definitionsfor the words; use them appropriately in sentences describing your mathwork.
  • Quadratic formula
  • Factoring
  • Completing the square
  • Discriminant

Your initial post should be at least 250 words in length.
