Polinomi | Polynomials #3

Neka je P(x) polinom trećeg stupnja čije su nultočke x_1, x_2, x_3. Ako je \frac{P(0.5)+P(-0.5)}{P(0)}=1011, odredi \frac{1}{x_1x_2}+\frac{1}{x_2x_3}+\frac{1}{x_3x_1}.
Let P(x) be a third degree polynomial with roots x_1, x_2, x_3. If \frac{P(0.5)+P(-0.5)}{P(0)}=1011, find the value of \frac{1}{x_1x_2}+\frac{1}{x_2x_3}+\frac{1}{x_3x_1}.
