حل {l}{y=x^2+4}{y=3x^3+2x+3}

$$\left\{ \begin{array} { l } { y = x ^ { 2 } + 4 } \\ { y = 3 x ^ { 3 } + 2 x + 3 } \end{array} \right.$$

حل مسائل y، x

$$x = \frac{2 ^ {\frac{2}{3}} {(\sqrt[3]{27 \sqrt{77} + 191} + \sqrt[3]{191 - 27 \sqrt{77}} + \sqrt[3]{2})}}{18} \approx 0.459863269$$

$$y = \frac{2 \cdot 2 ^ {\frac{2}{3}} \sqrt[3]{27 \sqrt{77} + 191} + \sqrt[3]{2} {(27 \sqrt{77} + 191)} ^ {\frac{2}{3}} + 2 \cdot 2 ^ {\frac{2}{3}} \sqrt[3]{191 - 27 \sqrt{77}} + \sqrt[3]{2} {(191 - 27 \sqrt{77})} ^ {\frac{2}{3}} + 582}{162} \approx 4.211474227$$
