  1. Question 1

    Q1. The condition that the roots of ax² + bx + c = 0 are in the ratio m:n is

    • A) mn b² = ac(m+n)²
    • B) mn b² = (m+n)² ac
    • C) b²(m+n) = mn ac
    • D) ac(m+n) = mn b

    Answer: mn b² = (m+n)² ac

    Explanation: Using the ratio of roots, we derive mn b² = (m+n)² ac.
