Solution - Simplification or other simple results

Step  1  :

Equation at the end of step  1  :

  (2a2 -  3a) -  2

Step  2  :

Trying to factor by splitting the middle term

 2.1     Factoring  2a²-3a-2 

The first term is,  2a²  its coefficient is  2 .
The middle term is,  -3a  its coefficient is  -3 .
The last term, "the constant", is  -2 

Step-1 : Multiply the coefficient of the first term by the constant   2 • -2 = -4 

Step-2 : Find two factors of  -4  whose sum equals the coefficient of the middle term, which is   -3 .

Step-3 : Rewrite the polynomial splitting the middle term using the two factors found in step 2 above,  -4  and  1 
                     2a² - 4a + 1a - 2

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

Final result :

  (a - 2) • (2a + 1)
