Today’s Question:

What does the acronym GCF mean, how do we find it and how do we use it to factor a polynomial?

Standard: MM1A1f- Factor expressions by GCF, grouping, trial and error, and special products.

What is the greatest common factor??

Factoring means to write as a product

Always look for a Greatest Common Factor 1st.

Factor 4x + 6y

What is their greatest common factor?

= 2( )

2x

+ 3y

Now, DIVIDE each term by the GCF.

Factor8a3 + 4a2 + 12a

What is their GCF?

= 4a( )

2a2

+ a

+ 3

Now, DIVIDE each term by the GCF.

40x2 – 100xy – 80y2

= 20( )

– 4y2

2x2

– 5xy

Factor2h2k + 2k

What is their GCF?

= 2k( )

+ 1

h2

Now, DIVIDE each term by the GCF.

12x5y2 + 9x4y2 - 6x3y2

= 3x3y2( )

+ 3x
