y=-02(x-30)^2+12 eching

$$y = - 02 ( x - 30 ) ^ { 2 } + 12$$

y uchun yechish

$$y=12$$

Chiziqli tenglamalarni yechish bo'yicha qadamlar

0 hosil qilish uchun 0 va 2 ni ko'paytirish.

$$y=0\left(x-30\right)^{2}+12$$

\left(a-b\right)^{2}=a^{2}-2ab+b^{2} binom teoremasini \left(x-30\right)^{2} kengaytirilishi uchun ishlating.

$$y=0\left(x^{2}-60x+900\right)+12$$

Har qanday sonni nolga ko‘paytirsangiz, nol chiqadi.

$$y=0+12$$

12 olish uchun 0 va 12'ni qo'shing.

$$y=12$$

x uchun yechish (complex solution)

$$x\in \mathrm{C}$$

$$y=12$$

x uchun yechish

$$x\in \mathrm{R}$$

$$y=12$$
