Question

P(x) = 6x³ - 3x² - x - 5 y Q(x) = x² + 2x + 4, calcula: a.P(x) + Q(x) b.Q(x) - P(x)

Answer 1

a. P (x)+Q(x) =6x³-3x²-x-5 + x²+2x+4 = 6x³-2x²+x-1
b. Q(x)-P(x) = x²+2x+4 - (6x³+3x²+x+5) = -6x³+4x²+3x+9

Answer 2

Respuesta:

P (x)+Q(x) =6x³-3x²-x-5 + x²+2x+4 = 6x³-2x²+x-1

Q(x)-P(x) = x²+2x+4 - (6x³+3x²+x+5) = -6x³+4x²+3x+9
