1 Oblicz wartości wielomianu w [latex](x)=(2x+1)^2 -2(x-2)-2(x-2)+3-2x^2[/latex] dla: x=-3 2 Dane są wielomiany  W [latex](x) =4x^3 -2x^2 -x+3,[/latex]Q(x)=[latex]8x-5[/latex],R(x)=x[latex]x^2 +x+2[/latex]oblicz3[latex]3*W (x)-2Q (x)*R (x)[/latex]

Zad.1 [latex]W(x)=(2x+1)^2 -2(x-2)-2(x-2)+3-2x^2=4x^2+4x+1-2x+4-2x+4+3-2x^2=2x^2+12=2*(-3)^2+12=2*9+12=18+12=30[/latex]   Zad.2 [latex]3W(x)-2Q(x)*R(x)=3(4x^3-2x^2-x+3)-2(8x-5)*(x^2+x+2)=12x^3-6x^2-3x+9-2*(8x^3+8x^2+16x-5x^2-5x-10)=12x^3-6x^2-3x+9-2(8x^3+3x+11x-10)=12x^3-6x^2-3x+9-16x^3-6x^2-22x+20=-4x^3-12x^2-25x+29[/latex]
