Question

Wykonaj działanie i zapisz wynik w najprostrzej postaci:

(2+√3)²-(1-√3)(1+√3)+(5-√3)²

Answer 1

(2+√3)²-(1-√3)(1+√3)+(5-√3)²=4+4√3+3-(1-3)+25-10√3+3=7+4√3+2+25-10√3+3=37-6√3

Answer 2

(2+√3)²-(1-√3)(1+√3)+(5-√3)²=(4+4√3+3)-(1-3)+(25-10√3+3)=
7+4√3+2+28-10√3=-6√3+37

Answer 3

(2+√3)²-(1-√3)(1+√3)+(5-√3)²= 4+4√3+3-(1+√3-√3-3)+25-10√3+3=
=4+4√3+3-1+3+25-10√3+3= -6√3 + 37
