Solution - Simplification or other simple results

Step  1  :

Equation at the end of step  1  :

  ((((9•(x2))-8)-11x2)+10)+10x
 Step  2  :

Equation at the end of step  2  :

  (((32x2 -  8) -  11x2) +  10) +  10x

Step  3  :

Step  4  :

Pulling out like terms :

 4.1     Pull out like factors :

   -2x² + 10x + 2  =   -2 • (x² - 5x - 1) 

Trying to factor by splitting the middle term

 4.2     Factoring  x² - 5x - 1 

The first term is,  x²  its coefficient is  1 .
The middle term is,  -5x  its coefficient is  -5 .
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   -5 .

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

Final result :

  -2 • (x2 - 5x - 1)
