Solution - Simplification or other simple results

Step  1  :

Equation at the end of step  1  :

  (3h2 +  11h) +  6

Step  2  :

Trying to factor by splitting the middle term

 2.1     Factoring  3h²+11h+6 

The first term is,  3h²  its coefficient is  3 .
The middle term is,  +11h  its coefficient is  11 .
The last term, "the constant", is  +6 

Step-1 : Multiply the coefficient of the first term by the constant   3 • 6 = 18 

Step-2 : Find two factors of  18  whose sum equals the coefficient of the middle term, which is   11 .

Step-3 : Rewrite the polynomial splitting the middle term using the two factors found in step 2 above,  2  and  9 
                     3h² + 2h + 9h + 6

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

Final result :

  (3h + 2) • (h + 3)
