Lutasin ang x=left(3y+2right)^3

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

I-solve ang x

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

Mga Hakbang ng Solution

Gamitin ang binomial theorem na \left(a+b\right)^{3}=a^{3}+3a^{2}b+3ab^{2}+b^{3} para palawakin ang \left(3y+2\right)^{3}.

$$x=27y^{3}+54y^{2}+36y+8$$

I-solve ang y (complex solution)

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

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

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

I-solve ang y

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