Zad 1 - oblicz zad 2 - uprosc wyrazenie zad 3 - oblicz   ZAŁĄCZNIK U DOŁU

Zad 1. [latex](2sqrt{3}-3sqrt{2})(sqrt{2}+sqrt{3})-(sqrt{4}-sqrt{6})=\2sqrt{6}+6-6-3sqrt{6}-sqrt{4}+sqrt{6}=-sqrt{4}[/latex] Zad 2. [latex]a)(x+frac{3}{2})-(x-frac{1}{2})=x+frac{3}{2}-x+frac{1}{2}=frac{4}{2}=2\\b)(5y+1)(1-5y)-(1+5y)^2=\5y-25y^2+1-5y-(1+10y+25y^2)=\5y-25y^2+1-5y-1-10y-25y^2=\-50y^2-20y=-10y(5y+2)[/latex] Zad 3. [latex](sqrt{3}-1)^2-(2-sqrt{3})^2=(3-2sqrt{3}+1)-(4-4sqrt{3}+3)=\3-2sqrt{3}+1-4+4sqrt{3}-3=2sqrt{3}-3[/latex]
