Question

solve the inequality using any method
x^2-8x+12<0

Answer 1

Princess, Key, or whoever you are -- it's disconcerting to see three similar problems in a row -- all from the same computer. Please stick with one name so that our tutors can help you better.

Answer 2

x^2-8x+12<0
(x-6)(x-2) < 0
so we have "critical" values at x=6 and x=2

mark these on a number line, yielding 3 sections
x<2, test at x=0 in (x-6)(x-2)<0, no!
x between 2 and 6 , test at x=5, yes!
x > 6 , test at x=10, no!

so 2 < x < 6
