If a zeros of a polynomial x3-3x2+x+1 are a-b, a,a+b, find a and b

1.	If a zeros of a polynomial x3-3x2+x+1 are a-b, a,a+b, find a and b
Answer» \xa0Given that the zeroes of the following polynomial are a-b, a and a+b :We are to find the\xa0values of a and b.We know that\xa0if p, q and r are the zeroes of a polynomial\xa0\xa0thenSo, for polynomial (i), we getandThus, the required value of a is 1 and that of b is ±√2.
