Let

\alpha ,\beta

are the roots of equation

2{x^2} - \left( {p + 1} \right)x + \left( {p - 1} \right) = 0

. If

\alpha - \beta = \alpha \beta

, then what is the value of

p

View answer and explanation

Correct option: B

Option B (2) is correct because it is the value of p that satisfies the given condition

\alpha - \beta = \alpha \beta
