\left\{ \begin{array} { l } { u + v = 4 } \\ { u \cdot v = t } \end{array} \right.
Whakaoti mō u, v, t (complex solution)
t\in \mathrm{C}\text{, }u=4-v\text{, }v=-\sqrt{4-t}+2
t\in \mathrm{C}\text{, }u=4-v\text{, }v=\sqrt{4-t}+2
Whakaoti mō u, v, t
t\leq 4\text{, }u=4-v\text{, }v=-\sqrt{4-t}+2
t\leq 4\text{, }u=4-v\text{, }v=\sqrt{4-t}+2
