  2. Box Factoring Solve by using the Box Factoring Method ? 2x2 + 10x + 8 = Izydorczak 2014

  3. Box Factoring Solve by using the Box Factoring Method 2x2 + 10x + 8 Can I reduce the polynomial first? How? Yes Izydorczak 2014

  4. Box Factoring Look for a number that can be taken out of each, using GCF. 2x2 + 10x + 8 Izydorczak 2014

  5. Box Factoring 2x2 +10x + 8 1 8 1 2 1 10 2 4 2 5 What is the GCF? Izydorczak 2014

  6. Box Factoring 2x2 +10x + 8 1 8 1 2 1 10 2 4 2 5 GCF = 2 Izydorczak 2014

  7. Box Factoring GCF = 2 2x2 +10x + 8 Divide each number by 2 Izydorczak 2014
