(2x^2+4-5)-(-8x+2+x^2)

 x2 + 8x - 3

Step-by-step explanation:

 1 . ((2x2 +  4) -  5) -  (x2 - 8x + 2)  

2.  Factoring  x2+8x-3  

The first term is,  x2  its coefficient is  1 .

The middle term is,  +8x  its coefficient is  8 .

The last term, "the constant", is  -3  

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

Step-2 : Find two factors of  -3  whose sum equals the coefficient of the middle term, which is   8 .

Step 3. -3

  +    

1

  =    

-2

-1

  +    

  3

  =    

2

Observation : No two such factors can be found !!  

Conclusion : Trinomial can not be factored
