Unit 5 day 1 Notes/HW – GCF & Special Patterns FactoringWarm-upFactor the following.a.6x2+x – 2b.4x2+ 11x + 6c.9x2– 27x + 20~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~Greatest Common Factor1. Look for common factors in the coefficients and constants. (prime factorization tree)2. Look at your variables. Look for the greatest number (smallest power) each term has in common for eachvariable in the expression.3. Put the Greatest Common Factor (GCF) in front of an open parenthesis and divide it from each term. Put thequotients in the parenthesis.Example:5x3+ 35xGCF of5and35is ____GCF of x3andxis ____therefore5x( ____+____ ) is the factored form!1.9x2+ 45x2.-14x4+ 5x23.45x2+ 10x4.3x2+ 24x + 455.33x2+ 22x + 116.12x4+ 8x2– 6x
