Solution - Simplification or other simple results

Step  1  :

Equation at the end of step  1  :

  (4 - 11x) +  7x2

Step  2  :

Trying to factor by splitting the middle term

 2.1     Factoring  7x²-11x+4 

The first term is,  7x²  its coefficient is  7 .
The middle term is,  -11x  its coefficient is  -11 .
The last term, "the constant", is  +4 

Step-1 : Multiply the coefficient of the first term by the constant   7 • 4 = 28 

Step-2 : Find two factors of  28  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,  -7  and  -4 
                     7x² - 7x - 4x - 4

Step-4 : Add up the first 2 terms, pulling out like factors :
                    7x • (x-1)
              Add up the last 2 terms, pulling out common factors :
                    4 • (x-1)
Step-5 : Add up the four terms of step 4 :
                    (7x-4)  •  (x-1)
             Which is the desired factorization

Final result :

  (x - 1) • (7x - 4)
