Common Factoring

 

Common factoring is the opposite of expanding!

Steps

Step 1 - Find the GCF 

 

Step 2 - Write the solution with brackets

Examples

1. 2x + 20          GCF = 2

   = 2 (x+10)

 

 

2. 14x^3 - 7x      GCF = 7x

   =7x (2x^2 - 1)

 

 

3. 21c^4d^3 - 28c^2d^5 + 7cd^3       GCF = 7cd^3

   =7cd^3 (3c^3 - 4cd^2 +1)
