Answer 1

Answer:

HOPE THIS ANSWER WILL REALLY HELPS YOU..

Answer 2

Step-by-step explanation:

let the number be 'y'which should be added to (x³-x²-x+1) to get (5x³-4x²+3x-1)

Now,

(x³-x²-x+1) + y = (5x³-4x²+3x-1)

or y = (5x³-4x²+3x-1) - (x³-x²-x+1)

or y = 5x³-4x²+3x-1 - x³+x²+x-1

or y = 4x³-3x²+4x-2

Answer: (4x³-3x²+4x-2) should be added to (x³-x²-x+1) to get (5x³-4x²+3x-1)
