engineering mathematics MCQ #4301

  1. Question 1

    Q1. If the roots of ax² + bx + c = 0 are in the ratio 2:3, then

    • A) 6b² = 25ac
    • B) 6b² = 25a + c
    • C) 25b² = 6ac
    • D) b² = 6ac / 25

    Answer: 6b² = 25ac

    Explanation: Using the ratio of roots, we get b²/a*c = (2+3)² / (2*3), simplifying to 6b² = 25ac.
