Question

1) Dados :
P(x) = 5 x² - x³ - 3
Q(x) = 3x² - 2x³ + x + 1
R(x) = x² - 2
S(x) = x + 3

Halla:
A) P(x) + Q (x)
B) P(x) - Q (x)
C) P (x) . S (x)
D)Q (x) : R (x)
E) P (x) : S (x)

Answer 1

A-(5x²-x³-3)+(3x² - 2x³ + x + 1)
    8x²-3x³+x-2
B-(5 x² - x³ - 3)-(3x² - 2x³ + x + 1)
     2x²+x³-x-4
C-(5 x² - x³ - 3)(x + 3)
5x³-x4-3x+15x²-3x³-9
