Respuesta:36+121c2-132c  

Final result :

 (11c - 6)2

Step by step solution :

Step  1  :

Equation at the end of step  1  :

 (36 +  112c2) -  132c

Step  2  :

Trying to factor by splitting the middle term

2.1     Factoring  121c2-132c+36  

The first term is,  121c2  its coefficient is  121 .

The middle term is,  -132c  its coefficient is  -132 .

The last term, "the constant", is  +36  

Step-1 : Multiply the coefficient of the first term by the constant   121 • 36 = 4356  

Step-2 : Find two factors of  4356  whose sum equals the coefficient of the middle term, which is   -132 .

     -4356    +    -1    =    -4357  

     -2178    +    -2    =    -2180  

     -1452    +    -3    =    -1455  

     -1089    +    -4    =    -1093  

     -726    +    -6    =    -732  

     -484    +    -9    =    -493  

     -396    +    -11    =    -407  

     -363    +    -12    =    -375  

     -242    +    -18    =    -260  

     -198    +    -22    =    -220  

     -132    +    -33    =    -165  

     -121    +    -36    =    -157  

     -99    +    -44    =    -143  

     -66    +    -66    =    -132    That's it

Step-3 : Rewrite the polynomial splitting the middle term using the two factors found in step 2 above,  -66  and  -66  

                    121c2 - 66c - 66c - 36

Step-4 : Add up the first 2 terms, pulling out like factors :

                   11c • (11c-6)

             Add up the last 2 terms, pulling out common factors :

                   6 • (11c-6)

Step-5 : Add up the four terms of step 4 :

                   (11c-6)  •  (11c-6)

            Which is the desired factorization

Multiplying Exponential Expressions :

2.2    Multiply  (11c-6)  by  (11c-6)  

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

In our case, the common base is  (11c-6)  and the exponents are :

         1 , as  (11c-6)  is the same number as  (11c-6)1  

and   1 , as  (11c-6)  is the same number as  (11c-6)1  

The product is therefore,  (11c-6)(1+1) = (11c-6)2  

Final result :

 (11c - 6)2
