Answer & Solution

Correct Answer

(A) -1

Step-by-step Solution

Detailed explanation

Given that \(\alpha, \beta, \gamma, 2\) and \(\varepsilon\) are roots of the equation \(x^5+4 x^4-13 x^3-52 x^2+36 x+144=0\) Put \(x=-2\) \(-32+64+104-208-72+144=0\) So, \(x=-2\) is also roots Put \(x=3\) \(243+324-351-468+108+144=0\) So, \(x=3\) is also roots…
