Question

se p(x)=2x3+x2+x-2eg(x)=x3-x2+x-1 calcule p(-1)+g(1).

Answer 1

Calcule p(-1) + g(1)

p(x) = 2x^3 + x^2 + x - 2
p(-1) = 2(-1)^3 + (-1)^2 + (-1) - 2
p(-1) = 2(-1) + 1 -1 - 2
p(-1) = -2 + 1 - 1 - 2
p(-1) = -1 -1 -2
p(-1) = -2 -2
p(-1) = - 4


g(x) = x^3 - x^2 + x - 1
g(1) = (1)^3 - (1)^2 + (1) - 1
g(1) = 1 - 1 + 1 - 1
g(1) = 0 + 1 - 1
g(1) = 1 - 1
g(x) = 0

Resolvemdo a operacao e substituindo :

= p(-1) + g (1)
= - 4 + 0
= - 4

Answer 2

Resposta:

Explicação passo-a-passo:

p(-1) + g(1)

p(x) = 2x^3 + x^2 + x - 2

p(-1) = 2(-1)^3 + (-1)^2 + (-1) - 2

p(-1) = 2(-1) + 1 -1 - 2

p(-1) = -2 + 1 - 1 - 2

p(-1) = -1 -1 -2

p(-1) = -2 -2

p(-1) = - 4

g(x) = x^3 - x^2 + x - 1

g(1) = (1)^3 - (1)^2 + (1) - 1

g(1) = 1 - 1 + 1 - 1

g(1) = 0 + 1 - 1

g(1) = 1 - 1

g(x) = 0

Resolvendo a operação e substituindo

= p(-1) + g (1)

= - 4 + 0

= - 4
