x(10x+1)(10x1)
x*(10x+1)*(10x-1)

Step by Step Solution

Step  1  :

Equation at the end of step  1  :

  (22•52x3) -  x

Step  2  :

Step  3  :

Pulling out like terms :

 3.1     Pull out like factors :

   100x3 - x  =   x • (100x2 - 1) 

Trying to factor as a Difference of Squares :

 3.2      Factoring:  100x2 - 1 

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 :  100  is the square of  10 
Check : 1 is the square of 1
Check :  x2  is the square of  x1 

Factorization is :       (10x + 1)  •  (10x - 1) 

Final result :

  x • (10x + 1) • (10x - 1)
