Answer 1

zad.1

x4 + px3 + rx +1 = (x2 + 2)2

x4 + px3 + rx +1 = x4 + 4x2 +4

p=0

g=4

r=0

zad.2

w(x) +p(x)

-2x3 + 5x2 - 3 + 2x3 + 12x = 5x2 + 12x -3

w(x) * p(x)

(-2x3 + 5x2 - 3)(2x3 + 12x) = -4x6 + 10x5 - 24x4 + 54x3 - 36x

zad.3

x3 - 7x2 - 4x + 28 = x2(x-7)-4(x-7) = (x-7)(x2-4) = (x-7)(x-2)(x+2)
