Factor By Grouping GCF Factoring twice!

Factor By Grouping Steps: Use GCF Factoring to factor the 1st two terms and last two terms separately Make sure the two parentheses match Write the answer as outside #s in one parentheses and inside #s in the other parentheses

Factor By Grouping Examples 10x3 – 5x2 + 14x - 7 GCF Factoring 5x2( ) + 7 ( ) Parentheses match? 5x2(2x – 1) + 7(2x - 1) (5x2 + 7)(2x – 1)

Factor By Grouping Examples 4rt – 6st – 10ru + 15su GCF Factoring 2t( ) – 5u( ) Parentheses match? 2t(2r – 3s) – 5u(2r – 3s) (2t – 5u)(2r – 3s)

Factor By Grouping Examples 12x3 – 9x2 + 28x – 21 GCF Factoring 3x2( ) + 7( ) Parentheses match? 3x2(4x – 3) + 7(4x – 3) (3x2 + 7)(4x – 3)

Factor By Grouping Examples 9x3 – x2 – 63x + 7 GCF Factoring x2( ) – 7( ) Parentheses match? x2(9x – 1) – 7(9x – 1) (x2 – 7)(9x – 1)
