Question

dado o polinômio p(x) =4x^2 + 6x^3 - 6x^2 - 8x + 16, calcule o valor numérico de p (x) para x= -1.

Answer 1

$6x^{3} + 4 x^{2} - 6 x^{2} -8x + 16$

$6x^{3} - 2x^{2} - 8x + 16$

$6(-1)^{3} - 2(-1)^{2} -8(-1) + 16 -6 - 2 + 8 + 16 -8 + 8 + 16 0 + 16 16$

Answer 2

Bom dia 

P(x) = 4x^2 + 6x^3 - 6x^2 - 8x + 16

P(1) = 4*(-1)^2 + 6*(-1)^3 - 6*(-1)^2 - 8*(-1) + 16
P(1) = 4 - 6 - 6 +  8 + 16 = 16
