Solution - Simplification or other simple results

Step  1  :

Equation at the end of step  1  :

  (3x2 -  8x) +  4

Step  2  :

Trying to factor by splitting the middle term

 2.1     Factoring  3x²-8x+4 

The first term is,  3x²  its coefficient is  3 .
The middle term is,  -8x  its coefficient is  -8 .
The last term, "the constant", is  +4 

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

Step-2 : Find two factors of  12  whose sum equals the coefficient of the middle term, which is   -8 .

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

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

Final result :

  (x - 2) • (3x - 2)
