Important Questions on Quadratic Equations for Practice
  1. The general form of a quadratic equation is (a ≠ 0)
    (a) ax² + bx + c                      (b) ax² + bx + c = 0
    (c) ax + b                                 (d) ax + b = 0
  2. Number of solutions of a quadratic equation are:
    (a) 0                                         (b) 1
    (c) 2                                         (d) 3
  3. If the equation x² – (2 + m) x + (– m² – 4m – 4) = 0 has coincident roots, then
    (a) m = 0, m = 1                   (b) m = 2, m = 2
    (c) m = – 2, m = – 2            (d) m = 6, m = 1
  4. If the roots of a quadratic equation are 2 and 3, then the equation is
    (a) x² + 5x + 6 = 0               (b) x² + 5x – 6 = 0
    (c) x² – 5x – 6 = 0               (d) x² – 5x + 6 = 0
