Solution - Simplification or other simple results

Step  1  :

Equation at the end of step  1  :

  ((2•3x2) +  x) -  1

Step  2  :

Trying to factor by splitting the middle term

 2.1     Factoring  6x²+x-1 

The first term is,  6x²  its coefficient is  6 .
The middle term is,  +x  its coefficient is  1 .
The last term, "the constant", is  -1 

Step-1 : Multiply the coefficient of the first term by the constant   6 • -1 = -6 

Step-2 : Find two factors of  -6  whose sum equals the coefficient of the middle term, which is   1 .

Step-3 : Rewrite the polynomial splitting the middle term using the two factors found in step 2 above,  -2  and  3 
                     6x² - 2x + 3x - 1

Step-4 : Add up the first 2 terms, pulling out like factors :
                    2x • (3x-1)
              Add up the last 2 terms, pulling out common factors :
                     1 • (3x-1)
Step-5 : Add up the four terms of step 4 :
                    (2x+1)  •  (3x-1)
             Which is the desired factorization

Final result :

  (3x - 1) • (2x + 1)
