Question 1033789: solve the inequality and express the solution using interval notation
x^2-7x+12>0
Answer by fractalier(6550) (Show Source): You can put this solution on YOUR website!
If we analyze
x^2-7x+12>0
we start by factoring it..we get
(x-3)(x-4) > 0
For us to have a product greater than zero, both factors have to be positive or both have to be negative...
For both to be positive, x has to be greater than 4.
For both to be negative, x has to be less than 3.
In interval notation, it looks like
(-infinity, 3) U (4, infinity)
