Solution - Simplification or other simple results

Step  1  :

Equation at the end of step  1  :

  (112x2 -  22x) +  1

Step  2  :

Trying to factor by splitting the middle term

 2.1     Factoring  121x²-22x+1 

The first term is,  121x²  its coefficient is  121 .
The middle term is,  -22x  its coefficient is  -22 .
The last term, "the constant", is  +1 

Step-1 : Multiply the coefficient of the first term by the constant   121 • 1 = 121 

Step-2 : Find two factors of  121  whose sum equals the coefficient of the middle term, which is   -22 .

Step-3 : Rewrite the polynomial splitting the middle term using the two factors found in step 2 above,  -11  and  -11 
                     121x² - 11x - 11x - 1

Step-4 : Add up the first 2 terms, pulling out like factors :
                    11x • (11x-1)
              Add up the last 2 terms, pulling out common factors :
                     1 • (11x-1)
Step-5 : Add up the four terms of step 4 :
                    (11x-1)  •  (11x-1)
             Which is the desired factorization

Multiplying Exponential Expressions :

 2.2    Multiply  (11x-1)  by  (11x-1) 

The rule says : To multiply exponential expressions which have the same base, add up their exponents.

In our case, the common base is  (11x-1)  and the exponents are :
          1 , as  (11x-1)  is the same number as  (11x-1)¹ 
 and   1 , as  (11x-1)  is the same number as  (11x-1)¹ 
The product is therefore,  (11x-1)⁽¹⁺¹⁾ = (11x-1)² 

Final result :

  (11x - 1)2
