If a and b are the two values of t that satisfy
the equation t2 – 6t + 8 = 0, with a > b, what is the value of a – b?  Choose the correct option
A) 2
B) 4
C) 6
D) 8
E) 10
Factor the left side of the equation:   t2 – 6t + 8 = 0   (t – 2)(t – 4) = 0   Split this equation into two equations and solve:   t – 2 = 0 t – 4 = 0   t = 2 t = 4   Thus, a = 4 and b = 2. So a – b = 4 – 2 = 2.   correct answer 2)2
