Solution - Simplification or other simple results

Step  1  :

            d
 Simplify   —
            d

Equation at the end of step  1  :

  (1 • x) • (x2 + x + 1)

Step  2  :

Trying to factor by splitting the middle term

 2.1     Factoring  x²+x+1 

The first term is,  x²  its coefficient is  1 .
The middle term is,  +x  its coefficient is  1 .
The last term, "the constant", is  +1 

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

Step-2 : Find two factors of  1  whose sum equals the coefficient of the middle term, which is   1 .

Observation : No two such factors can be found !!
Conclusion : Trinomial can not be factored

Final result :

  x • (x2 + x + 1)
