Question

Use the drop-down menus to complete the statements about factoring 14x2 + 6x – 7x – 3 by grouping.

Answer 1

Answer:

The GCF of the group (14x2 – 7x) is 7x

The GCF of the group (6x – 3) is 3

The common binomial factor is 2x-1

The factored expression is (7x+3)(2x-1)

Answer 2

Answer:1.  GCF of the group ( 6 x - 3 ) is 3.

2.  The common binomial factor is 2 x - 1.

3.  The factored expression is:  ( 2 x - 1 ) ( 7 x + 3 ).

Step-by-step explanation:

14 x² + 6 x - 7 x - 3 =

= ( 14 x² - 7 x ) + ( 6 x - 3 ) =

= 7 x ( 2 x - 1 ) + 3 ( 2 x - 1 ) =

= ( 2 x - 1 ) ( 7 x + 3 )
