y=4(x-2)(x-2) eching

$$y = 4 ( x - 2 ) ( x - 2 )$$

y uchun yechish

$$y=4\left(x-2\right)^{2}$$

Yechim qadamlari

\left(x-2\right)^{2} hosil qilish uchun x-2 va x-2 ni ko'paytirish.

$$y=4\left(x-2\right)^{2}$$

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

$$y=4\left(x^{2}-4x+4\right)$$

4 ga x^{2}-4x+4 ni ko'paytirish orqali distributiv xususiyatdan foydalanish.

$$y=4x^{2}-16x+16$$

x uchun yechish (complex solution)

$$x=-\frac{\sqrt{y}}{2}+2$$

$$x=\frac{\sqrt{y}}{2}+2$$

x uchun yechish

$$x=-\frac{\sqrt{y}}{2}+2$$

$$x=\frac{\sqrt{y}}{2}+2\text{, }y\geq 0$$
