Solution - Simplification or other simple results

Step  1  :

Equation at the end of step  1  :

  (2x25 • x) -  12
 Step  2  :
 Step  3  :

Pulling out like terms :

 3.1     Pull out like factors :

   2x²⁶ - 12  =   2 • (x²⁶ - 6) 

Trying to factor as a Difference of Squares :

 3.2      Factoring:  x²⁶ - 6 

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 : 6 is not a square !!

Ruling : Binomial can not be factored as the difference of two perfect squares.

Final result :

  2 • (x26 - 6)
