8. The cubic equation
$$a x ^ { 3 } + b x ^ { 2 } - 19 x - b = 0$$
where \(a\) and \(b\) are constants, has roots \(\alpha , \beta\) and \(\gamma\)
The cubic equation
$$w ^ { 3 } - 9 w ^ { 2 } - 97 w + c = 0$$
where \(c\) is a constant, has roots \(( 4 \alpha - 1 ) , ( 4 \beta - 1 )\) and \(( 4 \gamma - 1 )\)
Without solving either cubic equation, determine the value of \(a\), the value of \(b\) and the value of \(c\).
