If alpha, beta, gamma are roots of a cubic equation satisfyingthe relationsalpha + beta + gamma = 2,alpha^(2) + beta^(2) + gamma^(2) = 6 and alpha^(3) + beta^(3) + gamma^(3) = 8then the cubic equation is

Answer»

`X^(3) + 2X^(2) - x + 2 = 0 `
`x^(3) - 2x^(2) - x + 2 = 0 `
`x^(3) - 2x^(2) + x + 2 = 0 `
`x^(3) - 2x^(2) - x - 2 = 0`
