Wiedząc że
W(x)=x3- 4x2+ 6x i P(x) 3x3-6x2 -5x , oblicz W(x) + P(x), W(x)-P(x)
W9x) + P(x) = 4x3 - 10x2 + x
W(x) - P(x) = x3- 4x2+ 6x - (3x3-6x2 -5x) = x3 - 4x2+ 6x - 3x3 + 6x2 + 5x = -2x3 + 2x2 + 11x
W(x)+P(x)
dodajemy dwa wielomiany do siebie.
x3-4x2+6x+3x3-6x2-5x=4x3-10x2+x
W(x)-P(x)
odejmujemy dwa wielomiany od siebie
x3- 4x2+ 6x-(3x3-6x2 -5x)=
x3- 4x2+ 6x-3x2+6x2+5x=-2x3+2x2+11x
