\left\{ \begin{array} { l } { a + 3 b + 2 c + d = 7 } \\ { b + 3 c + d = 0 } \\ { 3 c + 5 d - a = 3 } \\ { a ^ { 2 } - 2 d + a = 0 } \end{array} \right.
Solve for a, b, c, d
a=\frac{-\sqrt{10185}-21}{58}\approx -2.102082086\text{, }b=\frac{13\sqrt{10185}+4971}{1682}\approx 3.735416108\text{, }c=\frac{-3\sqrt{10185}-2441}{1682}\approx -1.631249871\text{, }d=\frac{1176-2\sqrt{10185}}{841}\approx 1.158333505
a=\frac{\sqrt{10185}-21}{58}\approx 1.377944155\text{, }b=\frac{4971-13\sqrt{10185}}{1682}\approx 2.175404344\text{, }c=\frac{3\sqrt{10185}-2441}{1682}\approx -1.271247156\text{, }d=\frac{2\sqrt{10185}+1176}{841}\approx 1.638337125
