INTRODUCTORY EXERCISES

(3) Solve each of the following quadratic equations by factoring.
    (a) -11q + 2q2 + 5 = 0
    (b) 4u2 = 8u
SOLUTION: 
  (a) 2q2 - 11q  + 5 = 0   
      (2q - 10)(2q - 1) = 0
      (q - 5)(2q - 1) = 0
       q = 5  or q = 1/2

  (b) 4u2 = 8u
      4u2 - 8u = 0
      4u(u - 2) = 0
       u = 0 or u = 2
