Answer:

2

Step-by-step explanation:

x3(−5x+4)+5x−1=−39

−5x4+4x3+5x−1=−39

Step 1: Subtract -39 from both sides.

−5x4+4x3+5x−1−(−39)=−39−(−39)

−5x4+4x3+5x+38=0

Step 2: Factor left side of equation.

(−x+2)(5x3+6x2+12x+19)=0

Step 3: Set factors equal to 0.

−x+2=0 or 5x3+6x2+12x+19=0

x=2 or x=−1.409699
