Question 66526
x^2 - 6x > -8
x^2 - 6x + 8 > 0
x^2 - 4x - 2x + 8 > 0
(x^2 - 4x) + (-2x + 8) > 0
x(x - 4) - 2(x - 4) > 0
(x - 2)(x - 4) > 0
<========(2)---------(4)=========>
{{{x < 2}}} and {{{x > 4}}}
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
1/(t - 5) < 3/(t + 5)
(t^2 - 25)/(t - 5) < 3(t^2 - 25)/(t + 5)
t + 5 < 3(t - 5)
t + 5 < 3t - 15
20 < 2t
10 < t
