Question

Si P(x) = x2 – 2x – 1

Calcule: P(1) + P(2) + P(3)

Answer 1

     VALOR NUMÉRICO DE UN POLINOMIO

P(1) = (1)² - 2(1) - 1

P(1) = 1 - 2 - 1

P(1) = -2

P(2) = (2)² - 2(2) - 1

P(2) = 4 - 4 - 1

P(2) = -1

P(3) = (3)² - 2(3) - 1

P(3) = 9 - 6 - 1

P(3) = 2

P(1) + P(2) + P(3)

-2 + (-1) + 2

-2 - 1 + 2

-3 + 2

-1

RPTA: -1
