y=(x+2)^3+4 eching

$$y = ( x + 2 ) ^ { 3 } + 4$$

y uchun yechish

$$y=\left(x+2\right)^{3}+4$$

Yechim qadamlari

\left(a+b\right)^{3}=a^{3}+3a^{2}b+3ab^{2}+b^{3} binom teoremasini \left(x+2\right)^{3} kengaytirilishi uchun ishlating.

$$y=x^{3}+6x^{2}+12x+8+4$$

12 olish uchun 8 va 4'ni qo'shing.

$$y=x^{3}+6x^{2}+12x+12$$

x uchun yechish (complex solution)

$$x=\sqrt[3]{y-4}-2$$

$$x=-\left(e^{\frac{\pi i}{3}}\sqrt[3]{y-4}+2\right)$$

$$x=e^{\frac{2\pi i}{3}}\sqrt[3]{y-4}-2$$

x uchun yechish

$$x=\sqrt[3]{y-4}-2$$
