Answer:

 -294    +    1    =    -293  

     -147    +    2    =    -145  

     -98    +    3    =    -95  

     -49    +    6    =    -43  

     -42    +    7    =    -35  

     -21    +    14    =    -7  

     -14    +    21    =    7  

     -7    +    42    =    35    That's it

Step-3 : Rewrite the polynomial splitting the middle term using the two factors found in step 2 above,  -7  and  42  

                    49x2 - 7x + 42x - 6

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

                   7x • (7x-1)

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

                   6 • (7x-1)

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

                   (7x+6)  •  (7x-1)

            Which is the desired factorization
