Zadanie 2[tex]W(x)=\sqrt{5}x^3-x^2-\sqrt{5}x+1=x^2(\sqrt{5}x-1)-(\sqrt{5}x-1)=\\\\=(\sqrt{5}x-1)(x^2-1)=\boxed{(\sqrt{5}x-1)(x+1)(x-1)}[/tex]
Zadanie 3[tex]W(x)=8x^5+16x^3-x^2-2=8x^3(x^2+2)-(x^2+2)=\\\\=(x^2+2)(8x^3-1)=\boxed{(x^2+2)(2x-1)(4x^2+2x+1)}[/tex]
Zadanie 4[tex]W(x)=x^5-\sqrt{2}x^4+\sqrt{3}x^3-\sqrt{6}x^2=x^2(x^3-\sqrt{2}x^2+\sqrt{3}x-\sqrt{6})=\\\\=x^2(x^2(x-\sqrt{2})+\sqrt{3}(x-\sqrt{2}))=\boxed{x^2(x-\sqrt{2})(x^2+\sqrt{3})}[/tex]
