InterviewSolution

1.	Verify that 3,-1,-1/3 are the zeros of the cubic polynomial `p(x)=3x^3-5x^2-11x-3`. verify the relationship between the zeros and its coefficients.
Answer» `F(x)=(x-3)(x+1)(x+1/3)` `=(x^2-3x+x-3)(x+1/3)` `=(x^2-2x-3)(x+1/3)` `=x^3-2x^2-3x+1/3x^2-2/3x-1` `F(x)=x^3-5/3x^2-11/3x-1`
