Pulling out like terms

6.1     Pull out like factors :

  6x3 - 9x  =   3x • (2x2 - 3)  

Trying to factor as a Difference of Squares:

6.2      Factoring:  2x2 - 3  

Theory : A difference of two perfect squares,  A2 - B2  can be factored into  (A+B) • (A-B)

Proof :  (A+B) • (A-B) =

        A2 - AB + BA - B2 =

        A2 - AB + AB - B2 =

        A2 - B2

Note :  AB = BA is the commutative property of multiplication.

Note :  - AB + AB equals zero and is therefore eliminated from the expression.

Check :  2  is not a square !!

Ruling : Binomial can not be factored as the

difference of two perfect squares

Final result :

 3x • (2x2 - 3)
