Question

1 - Considerando os polinômios abaixo, determine o polinômio O(x) = P(x) + Q(x).
P(x)= 6x5 + 8x3+5x+2 e Q(x) = 3x5 - 6x3-2x-10

A) Q(x) = 7x5+2x3+4x-7
B)Q(x) = 9x5+2x3+3x-8
C)Q(x) = 9x5+14x3+3x-12
D)Q(x) = 3x5+2x3+3x-8

Answer 1

Resposta:

item b) 9x⁵ +2x³ +3x - 8

Explicação passo-a-passo:

P(x)= 6x⁵ +8x³ +5x +2

Q(x)= 3x⁵ - 6x³ -2x -10

O(x) = P(x) + Q(x)

O(x)= 6x⁵ +8x³ +5x +2 + (3x⁵ - 6x³-2x -10)

O(x)= 6x⁵+8x³ +5x +2 +3x⁵ -6x³ -2x -10

O(x)= 6x⁵ +3x⁵ +8x³ -6x³ +5x -2x +2 -10

O(x)= 9x⁵ +2x³ +3x -8
