x%5E2-6x%2B8=0...first factor completely (or use quadratic formula) to find roots
x%5E2-6x%2B8=0.....write -6x as -4x-2x
x%5E2-4x-2x%2B8=0........group
%28x%5E2-4x%29-%282x-8%29=0
x%28x-4%29-2%28x-4%29=0
%28x-2%29%28x-4%29=0
roots:
if %28x-2%29=0...=>..x=2
if %28x-4%29=0...=>..x=4

so, your answer is: They are both positive.
