  1. Question 1

    Q1. The equation x² + px + q = 0 has roots α, β. If the equation x² + px + r = 0 has roots α, γ, then (β - γ)r =

    • A) q - r
    • B) r - q
    • C) q + r
    • D) r / q

    Answer: r - q

    Explanation: Using the sum and product of roots for both equations, we derive (β - γ)r = r - q.
