Practice Set 2.2

  1. Solve the following quadratic equations by factorisation.
    (1) x2 – 15 x + 54 = 0 (2) x2 + x – 20 = 0 (3) 2y2 + 27 y + 13 = 0
    (4) 5m2 = 22 m + 15 (5) 2x2 – 2 x +1/2 = 0 (6) 6x -2/x = 1

(8) 3x2 – 2 6 x + 2 = 0 (9) 2m (m – 24) = 50
(10) 25m2 = 9 (11) 7m2 = 21m (12) m2 – 11 = 0
