Question :-
If the zeros of polynomial x^3 - 3x^2 + x + 1 are a - b, a, a + b, find a and b ?
____________________
Solution :-
Given Information :-
• a polynomial is given, P(x)=
• Zeroes = (a-b), a, (a+b)
To Find :-
• We have to find the value of a and b
Calculation :-
The given polynomial is a cubic polynomial and the given zeroes are (a-b),a, (a+b)
Also,
From, P(x) =
- a = 1
- a = 1b = -3
- a = 1b = -3 c = 1
So,
Now,
Using this formula,
Using this formula, We get,
Putting the value of a = -1
Cancellation of the negative sign on both the sides,
Cancellation of the negative sign on both the sides,We get,

Final Answer :-
- a = 1
- b = ±
