Solution - Simplification or other simple results

Step  1  :

Equation at the end of step  1  :

  (2x2 -  34x) -  72

Step  2  :

Step  3  :

Pulling out like terms :

 3.1     Pull out like factors :

   2x² - 34x - 72  =   2 • (x² - 17x - 36) 

Trying to factor by splitting the middle term

 3.2     Factoring  x² - 17x - 36 

The first term is,  x²  its coefficient is  1 .
The middle term is,  -17x  its coefficient is  -17 .
The last term, "the constant", is  -36 

Step-1 : Multiply the coefficient of the first term by the constant   1 • -36 = -36 

Step-2 : Find two factors of  -36  whose sum equals the coefficient of the middle term, which is   -17 .

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

Final result :

  2 • (x2 - 17x - 36)
