If a and b are the two values of t that satisfy
the equation t^2 â€“ 10t + 16 = 0, with a > b, what is the value of a â€“ b?
Choose the correct choice from the following
A) 2 B) 4 C) 6 D) 8 E) 10
Factor the left side of the equation:   t^2 â€“ 10t + 16 = 0   (t â€“ 2)(t â€“ 8) = 0   t = 2, t = 8   Thus, a = 8 and b = 2. So a â€“ b = 8 â€“ 2 = 6.   The answer is 6.
