Solution - Simplification or other simple results

Step  1  :

Equation at the end of step  1  :

  (22x2 -  4x) -  3

Step  2  :

Trying to factor by splitting the middle term

 2.1     Factoring  4x²-4x-3 

The first term is,  4x²  its coefficient is  4 .
The middle term is,  -4x  its coefficient is  -4 .
The last term, "the constant", is  -3 

Step-1 : Multiply the coefficient of the first term by the constant   4 • -3 = -12 

Step-2 : Find two factors of  -12  whose sum equals the coefficient of the middle term, which is   -4 .

Step-3 : Rewrite the polynomial splitting the middle term using the two factors found in step 2 above,  -6  and  2 
                     4x² - 6x + 2x - 3

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

Final result :

  (2x - 3) • (2x + 1)
