r^2+n-16^2=0 eching

$$r ^ { 2 } + n - 16 ^ { 2 } = 0$$

n uchun yechish

$$n=256-r^{2}$$

Yechim qadamlari

2 daraja ko‘rsatkichini 16 ga hisoblang va 256 ni qiymatni oling.

$$r^{2}+n-256=0$$

Ikkala tarafdan r^{2} ni ayirish. Har qanday sonni noldan ayirsangiz, o‘zining manfiyi chiqadi.

$$n-256=-r^{2}$$

256 ni ikki tarafga qo’shing.

$$n=-r^{2}+256$$

r uchun yechish

$$r=\sqrt{256-n}$$

$$r=-\sqrt{256-n}\text{, }n\leq 256$$
