 get : x 2 + 1 = Ax(x – 1)2 + Bx(x – 1) + C x + D(x – 1)3 I

The two zeroing numbers are x = 1 and x = 0: sox = 1: 1 + 1 = 0 + 0 + C + 0, so C = 2
 
x = 0: 1 = 0 + 0 + 0 – D,
 so D = –1


 
The particular x-values I choose aren't important, so I'll pick smallish ones:x = 2:   (2)2 + 1 = A(2)(2 – 1)2 + B(2)(2 – 1) + (2)(2) + (–1)(2 – 1)3 


4 + 1 = 2A + 2B + 4 – 1 


5 = 2A + 2B + 3 


1 = A + Bx = –1:(–1)2 + 1 = A(–1)(–1 – 1)2 + B(–1)(–1 – 1) + (2)(–1) + (–1)(–1 – 1)3
 

1 + 1 = –4A + 2B – 2 + 8 


2 = –4A + 2B + 6 


2A – B = 2......


Please mark it as brainiest answer ..............
