a) P(x) + G (x) =
b) P(x) - G (x) =
c) P(x) x G (x) =
d) G (x) +P(x) =
e) G (x) - P(x) =

Answer 1

Resposta:

Explicação passo-a-passo:

P(x)= 4x² – 10x – 5 e G(x)= 6x + 12

a) P(x) + G (x) =

(4x² – 10x – 5) + (6x + 12)

4x² - 4x + 7

b) P(x) - G (x) =

(4x² – 10x – 5) - (6x + 12)

4x² - 16x - 17

c) P(x) x G (x) =

(4x² – 10x – 5) x (6x + 12)

24x³ + 48x² - 24x² - 120x - 30x - 60

24x³ + 24x² - 150x - 60

d) G (x) +P(x) =

(6x + 12) + (4x² – 10x – 5)

4x² - 4x + 7

e) G (x) - P(x) =

(6x + 12) - (4x² – 10x – 5)

- 4x² + 16x + 17
