Q14 of 113 Page 71

If α, β, γ are the zeros of the polynomial p(x) = 6x3 + 3x2 – 5x + 1, find the value of .

It is given in the question that,

p (x) = 6x3 + 3x2 – 5x + 1


= 6x3 – (- 3) x2 + (- 5) x – 1


Now by comparing the polynomial with x3 – x2 () + x ( – , we get:


= - 5 and,


= - 1


()


= ()


= ()


= 5
