Dane są wielomiany: W(X)= x^3-2x+1 a(X) =-x^3+3x P(X)=2x+3 Wykonaj działania: W(X)=-P(X)+a (X) 2w(X)-5a(X)+W(X)·P(X) Prosze o rozwiązanie! :)

w(x) = [latex] x^{3} -2x +1[/latex] a(x) = [latex] -x^{3} +3x[/latex] p(x) = 2x + 3 w(x) = - p(x) + a(x) [latex] x^{3} - 2x +1[/latex] = [latex]- (2x +3) + ( - x^{3} + 3x)[/latex] [latex] x^{3} -2x +1 [/latex] = [latex]-2x-3- x^{3} +3x[/latex] [latex] x^{3} -2x +1 = - x^{3} +3x -3 [/latex] [latex] x^{3} -2x +1 -2x -3 + x^{3} - 3x = 0 [/latex] [latex] 2x^{3} - 7x +1 = 0[/latex] teraz te drugie
