Project #31224 - Factoring

For the problems on page 345-6, factor the polynomials using whatever strategy seems appropriate. State what methods you will use and then demonstrate the methods on your problems, explaining the process as you go. Discuss any particular challenges those particular polynomials posed for the factoring.

·  w2 + 30w + 81

·  ac + xc + aw2 + xw2

 

 

For the problem on page 353 make sure you use the “ac method” regardless of what the book’s directions say. Show the steps of this method in your work in a similar manner as how the book shows it in examples.

10A^2 - 27AB + 5b^2

The ac Method

The first step in factoring ax2 + bx + c with a = 1 is to find two numbers with a product of c and a sum of b. If a ≠ 1, then the first step is to find two numbers with a product of ac and a sum of b. This method is called the ac method. The strategy for factoring by the ac method follows. Note that this strategy works whether or not the leading coefficient is 1.

 

 

Incorporate the following five 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.):

    • Factor  
    • GCF  
    • Prime factors  
    • Perfect square 
    • Grouping

Your initial post should be 150-250 words in length
