  1. Question 1

    Q1. The general equation of a conic is Ax² + Bxy + Cy² + Dx + Ey + F = 0. Which discriminant determines the type of conic?

    • A) B² - 4AC
    • B) 4AC - B²
    • C) B² + 4AC
    • D) A² + B² + C²

    Answer: B² - 4AC

    Explanation: The discriminant B² - 4AC determines the conic: <0 (ellipse), =0 (parabola), >0 (hyperbola).
