Factoring out GCF
The first step in factoring is to determine its greatest monomial factor. If there is a greatest monomial factor other than 1, use the distributive property to rewrite the given polynomial as the product of this greatest monomial factor and a polynomial.
Example 1 Factor each polynomial.
a) 6x4 15x3 + 3x2
3x2 (2x2 5x + 1)
GCF: 3x2
Reduce each term of the polynomial dividingby the GCF
Find the GCF 3x23x2 3x2 3x2
