Solution - Simplification or other simple results

Step  1  :

Equation at the end of step  1  :

  (2x2 -  11x) +  9

Step  2  :

Trying to factor by splitting the middle term

 2.1     Factoring  2x²-11x+9 

The first term is,  2x²  its coefficient is  2 .
The middle term is,  -11x  its coefficient is  -11 .
The last term, "the constant", is  +9 

Step-1 : Multiply the coefficient of the first term by the constant   2 • 9 = 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,  -9  and  -2 
                     2x² - 9x - 2x - 9

Step-4 : Add up the first 2 terms, pulling out like factors :
                    x • (2x-9)
              Add up the last 2 terms, pulling out common factors :
                     1 • (2x-9)
Step-5 : Add up the four terms of step 4 :
                    (x-1)  •  (2x-9)
             Which is the desired factorization

Final result :

  (2x - 9) • (x - 1)
