• v1.01: Page 165 Answer 19 - Correct answer solution is -  (ax+2)(x+6) = (x+4)^2+c  --> ax^2+6ax+2x+12 = x^2+8x+16+c. Since the expressions are equivalent, they have infinitely many solutions. Hence, a = 1 and 12 = 16+c --> c  = -4. a - c = 1 –(-4) = 5.

• v1.02 Page 165 Answer 19 - ax^2+6ax+2x-12 was changed to ax^2+6ax+2x+12.
