zad1 Rozłóż wielomian "w" na czynniki.

a) w(x) = x3 - x2 + 8x - 8

b) w(x) = x3 + 5x2 - 4x -20

c) w(x) = x3 - 2x2 - 9x + 18

d) w(x) = -x3 - 3x2 + 4x + 12

e) w(x) = -2x3 + 10x2 -x +5

f) w(x) = -4x3 + 8x2 + x -2

zad2 Uzasadnij, że wielomian "w" nie da się rozłożyć na czynniki liniowe.

a) w(x) = x6 - 27x3

b) w(x) = x5 + 125x2

c) w(x) = -x4 -64x

a) w(x) = (x2 - 1) (x2 - 4x + 4)

b) w(x) = (x3 - 1) (x2 + 6x +9)

c) w(x) = (x3 - x) (x3 + 2x2 + x)

d) w(x) = x4 - 2x3 - 4x2 + 8x
