Question

dados los siguientes polinomios
M (X) = 5x² + x³ - 2
N (X) = - x³ + 5
R (X) = - x⁴ - x+ 3
S (X) = x² - x + 2
Se pide efectuar=
a) M (x) + N (x)
b) R (x) + S (x)
c) R (x) - N (x)
d) R (x) - S (x)

porfavor ayuda​

Answer 1

Respuesta:

a) M (x) + N (x) = 5x² + 3

b) R (x) + S (x) = - x⁴ + x² - 2x + 5

c) R (x) - N (x) = - x⁴ + x³ - x - 2

d) R (x) - S (x) = - x⁴ - x² + 1

Explicación paso a paso:

M (x) = 5x² + x³ - 2

N (x) = - x³ + 5

R (x) = - x⁴ - x + 3

S (x) = x² - x + 2

Se pide efectuar:

a) M (x) + N (x) = (5x² + x³ - 2) + (- x³ + 5)

   M (x) + N (x) = 5x² + x³ - 2 - x³ + 5

   M (x) + N (x) = 5x² + 3

b) R (x) + S (x) = (- x⁴ - x + 3) + (x² - x + 2)

   R (x) + S (x) = - x⁴ - x + 3 + x² - x + 2

   R (x) + S (x) = - x⁴ + x² - 2x + 5

c) R (x) - N (x) = (- x⁴ - x + 3) - (- x³ + 5)

   R (x) - N (x) = - x⁴ - x + 3 + x³ - 5

   R (x) - N (x) = - x⁴ + x³ - x - 2

d) R (x) - S (x) = (- x⁴ - x + 3) - (x² - x + 2)

   R (x) - S (x) = - x⁴ - x + 3 - x² + x - 2

   R (x) - S (x) = - x⁴ - x² + 1

Espero haberte ayudado.   :))
