Question

Considere os polinômios, P(x)=4x5+7x3–9x+2 Q(x)=x5+2x4−7x3+5x, Calcule:
f) P(x) + Q (x) =
g) P(x) - Q(x) =
h) Q (x) +P(x) =
i) Q(x) - P(x) =

Answer 1

Resposta:

f) P(x) + Q (x) = 5x⁵+2x⁴-4x+2

g) P(x) - Q(x) =3x⁵-2x⁴+14x³-14x+2

h) Q (x) +P(x) =5x⁵+2x⁴-4x+2

i) Q(x) - P(x) =-3x⁵+2x⁴-14x³+14x-1
