7 By finding a cubic equation whose roots are \(\alpha , \beta\) and \(\gamma\), solve the set of simultaneous equations
$$\begin{aligned}
\alpha + \beta + \gamma & = - 1 ,
\alpha ^ { 2 } + \beta ^ { 2 } + \gamma ^ { 2 } & = 29 ,
\frac { 1 } { \alpha } + \frac { 1 } { \beta } + \frac { 1 } { \gamma } & = - 1 .
\end{aligned}$$
