Question

Sendo os Polinômios P(x) = 2x 5 + 2 x 3 + 3x 2 + 4x + 6 e
Q(x) = -3x 4 - 2 x 3 + x 2 – x + 16 . Determine P(x) - Q(x).

Answer 1

Explicação passo-a-passo:

P(x):

P(x) = 2x 5 + 2 x 3 + 3x 2 + 4x + 6

0=10+6+6+4x6

0=28+4x

-4x=28

x=-7

Q(x):

Q(x) = -3x 4 - 2 x 3 + x 2 – x + 16

0=-12-6+x

0=-18+x

-x=-18

x=18
