Zad 1.

Dla jakiej wartości parametru m liczba a jest pierwiastkiem wielomianu w?

a) w(x) = -3x³ + 2x² +mx - 3 a = 1

b) w(x) = x³ + (2m - 1)x² - 3x + 7 a = 2

c) w(x) = - x³ + mx² - mx + 5 a = 3

d) w(x) = x³ + 3x² + (m² - 2m)x + 2 a = - 2

Zad.2. Rozłóż wielomian na czynniki i podaj jego pierwiastki.

a) w(x) = 5x⁵ - 10x³ + 5x

b) w(x) = - 3x⁵ + 30x³ - 75x

c) w(x) = 32x⁶ - 16x⁴ + 2x²

d) w(x) = - 125x³ - 27

e) w(x) = 8x⁴ + 27x

f) w(x) = - 14x³ + 7x
