Solution - Simplification or other simple results

Step  1  :

Equation at the end of step  1  :

  1 -  32m2

Step  2  :

Trying to factor as a Difference of Squares :

 2.1      Factoring:  1-9m² 

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 :  1  is the square of  1 
Check : 9 is the square of 3
Check :  m²  is the square of  m¹ 

Factorization is :       (1 + 3m)  •  (1 - 3m) 

Final result :

  (3m + 1) • (1 - 3m)
