Yechim qadamlari

Ko‘paytirish qoida yordamida turli kvadratlarga aylantirilishi mumkin: \left(a-b\right)\left(a+b\right)=a^{2}-b^{2}.

$$\left(2\sqrt{3}\right)^{2}-1^{2}$$

\left(2\sqrt{3}\right)^{2} ni kengaytirish.

$$2^{2}\left(\sqrt{3}\right)^{2}-1^{2}$$

2 daraja ko‘rsatkichini 2 ga hisoblang va 4 ni qiymatni oling.

$$4\left(\sqrt{3}\right)^{2}-1^{2}$$

\sqrt{3} kvadrati – 3.

$$4\times 3-1^{2}$$

12 hosil qilish uchun 4 va 3 ni ko'paytirish.

$$12-1^{2}$$

2 daraja ko‘rsatkichini 1 ga hisoblang va 1 ni qiymatni oling.

$$12-1$$

11 olish uchun 12 dan 1 ni ayirish.
