Question

CALCULE O POLINÔMIO P(X)= 3x²+12x-7 para que seja P(-2), P(0), (Pi)

Answer 1

P(-2) = 3.(-2)² + 12.(-2) - 7
P(-2) = 3.4 - 24 - 7
P(-2) = 12 - 24 - 7
P(-2) = -19

P(0) = 3.0 + 12.0 - 7
P(0) = 0 + 0 - 7
P(0) = -7

P(i) = 3.i² + 12i - 7
P(i) = 3.(-1) + 12i - 7
P(i) = -3 + 12i - 7
P(i) = -10 + 12i
