Answer:
 -x • (x2 - 5x + 1) • (3x - 4)
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 !!
