Wiedząc, że:
W(x) = 4x^3 - 2x^2 + x - 2,
P(x) = x^3 + 3x + 1 i
Q(x) = 2x^4 + x^3 - x + 6,
Wykonaj działania:
W(x) + P(x) =
P(x) + a(x) =
" Life is not a problem to be solved but a reality to be experienced! "

W(x) + P(x) = 4x^3 - 2x^2 + x - 2 + x^3 + 3x + 1 = 5x^3 - 2x^2 + 4x - 1 = 5x^3 - 2x^2 + 4x - 1
P(x) + Q(x) = x^3 + 3x + 1 + 2x^4 + x^3 - x + 6 = 2x^4 + 2x^3 + 2x + 7
