The Greatest Common Factor
-
To factor an expression means to rewrite the expression as an equivalent product.
-
The greatest common factor (or GCF) is the largest factor common to all terms in the polynomial
Examples: Factor each polynomial.
1.
6 is the only factor all 3 terms share
Factoring out is simply dividing the GCF out of each term
Rewrite as product of GCF and remaining polynomial
2.
-13 is the common factor
All terms have -13 in common (can always factor negative if necessary)
Factoring out a negative changes all signs on remaining polynomial
3.
All have
in common
Divide each by the common factor
Note the dividing by itself yields a 1, does not cancel out term
