Yechim qadamlari

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

$$n^{2}-\left(2\sqrt{x}\right)^{2}$$

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

$$n^{2}-2^{2}\left(\sqrt{x}\right)^{2}$$

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

$$n^{2}-4\left(\sqrt{x}\right)^{2}$$

2 daraja ko‘rsatkichini \sqrt{x} ga hisoblang va x ni qiymatni oling.

$$n^{2}-4x$$

x ga nisbatan hosilani topish
