Answer:
  -x • (x2 - 5x + 1) • (3x - 4)
Step-by-step explanation:
STEP
1: Equation at the end of step 1
  (((x2) -  5x) +  1) • (4x -  3x2)
STEP2:STEP
2:Pulling out like terms
  Pull out like factors :
 4x - 3x2  =   -x • (3x - 4) 
Trying to factor by splitting the middle term
  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 .
      -1    +    -1    =    -2	
      1    +    1    =    2	
Observation : No two such factors can be found !!
