Question

5 ejercicios de multiplicacion de polinomio​

Answer 1

Respuesta:

a) P(x) + Q(x)

a) P(x) + Q(x) = 5x2 - 7x + 3 - 5x2 + 2x =

= 5x2 - 5x2 - 7x + 2x + 3 = -5x + 3

b) P(x) + R(x))

b) P(x) + R(x) = 5x2 - 7x + 3 + x3 + x2 + 2 =

= x3 + 5x2 + x2 - 7x + 3 + 2 = x3 + 6x2 - 7x + 5

P(x) = 5x2 - 7x + 3

Q(x) = -5x2 + 2x

R(x) = x3 + x2 + 2

c) Q(x) + R(x)

c) Q(x) + R(x) = -5x2 + 2x + x3 + x2 + 2 =

= x3 - 5x2 + x2 + 2x + 2 = x3 - 4x2 + 2x + 2
