a) u(x) = 2 * w(x) + (1-x) * p(x) =
= 2 * (x³-1) + (1-x)*(2x²+4x+1) =
= 2x³ - 2 + (2x²+4x+1-2x³-4x²-x) =
= 2x³ - 2 + 2x² + 4x + 1 - 2x³ - 4x² - x
= -2x² + 3x - 1
Wielomian drugiego stopnia
b) u(x) = (x-2) * w(x) - 3 * p(x) =
= (x-2)(x³-1) - 3 * (2x²+4x+1) =
= x⁴ - x - 2x³ + 2 - (6x²+12x+3) =
= x⁴ - 2x³ - x + 2 - 6x² - 12x - 3 =
= x⁴ - 2x³ - 6x² - 13x - 1
Wielomian czwartego stopnia
