<h3><u>Question</u> :-</h3>
Is (x-2) is a factor of x³-3x²-x +7 –
<h3><u>Explanation</u> :-</h3>
We are given –
- Polynomial function, P(x) = x³-3x²-x +7
- In order to check if x - 2 is a factor of x³-3x²-x +7 or not, we must show that P(2) = 0.





Now Put x = 2 into the polynomial –





- Since the value of the polynomial function st x = 2 is not Zero (0). Henceforth, ( x - 2) is a factor of x³-3x²-x +7.
