Expanding the left side of the equation gives $x^3 + 8x = 3 + x^3$. Subtracting $x^3$ from both sides simplifies to $8x = 3$, leading to $x = \frac{3}{8}$.

Solve the Equation x(x2+8)=3+x3x \left( x ^ { 2 } + 8 \right) = 3 + x ^ { 3 }x(x2+8)=3+x3

Solve the Equation $x \left( x ^ { 2 } + 8 \right) = 3 + x ^ { 3 }$
