Solution - Simplification or other simple results

Step  1  :

Equation at the end of step  1  :

  ((2•32x2) +  15x) +  3

Step  2  :

Step  3  :

Pulling out like terms :

 3.1     Pull out like factors :

   18x² + 15x + 3  =   3 • (6x² + 5x + 1) 

Trying to factor by splitting the middle term

 3.2     Factoring  6x² + 5x + 1 

The first term is,  6x²  its coefficient is  6 .
The middle term is,  +5x  its coefficient is  5 .
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   5 .

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 :

  3 • (3x + 1) • (2x + 1)
