The roots of the equation \(x^3-3 x-2=0\) are
- A \(-1,-1,2\)
- B \(-1,1,-2\)
- C \(-1,2,-3\)
- D \(-1,-1,-2\)
Answer & Solution
Correct Answer
(A) \(-1,-1,2\)
Step-by-step Solution
Detailed explanation
Given equation is \(x^3-3 x-2=0\) Now, put \(x=-1\), we get \(\begin{aligned} (-1)^3-3(-1)-2 & =0 \\ \Rightarrow \quad 0 & =0 \end{aligned}\) Given equation can be written as…
