Solution - Simplification or other simple results

Step  1  :

Evaluate an expression :

 1.1    Multiply  (11-2x)  by  (11-2x) 

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

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

Equation at the end of step  1  :

  (4 • (x2)) -  (11 - 2x)2
 Step  2  :

Equation at the end of step  2  :

  22x2 -  (11 - 2x)2

Step  3  :

 3.1     Evaluate :  (11-2x)2   =    121-44x+4x2 

Step  4  :

Pulling out like terms :

 4.1     Pull out like factors :

   44x - 121  =   11 • (4x - 11) 

Final result :

  11 • (4x - 11)
