2.5 Factoring Using Grid

  1. 1. 2.5 Factoring Algebraically (Grouping) 1 March 12, 2014 2.5 Factoring (Part 2) Using Grouping (i.e algebraically)
  2. 2. 2.5 Factoring Algebraically (Grouping) 2 March 12, 2014 Grouping is very similar to the GRID method...
  3. 3. 2.5 Factoring Algebraically (Grouping) 3 March 12, 2014 Example: x2 + 5x + 6 Psst... we've done this before, it's (x+2)(x+3) Step 1. Multiply a c and find factors that add to b. Step 2. Break into 2 groups Step 3. Factor each group (i.e. find the GCF and divide each term) Step 4: Take one of the twin groups and then put the GCFs of each group into one set of brackets.
  4. 4. 2.5 Factoring Algebraically (Grouping) 4 March 12, 2014 Example: Factor x2 + 3x - 54
