I'm trying my best to understand these type of questions but I am having some trouble. Here's what I've got:
1) x^2 + 2x > 3
x^2 + 2x - 3 > 0
(x - 1)(x + 3) > 0
1 > x > - 3 => interval: [1,-3] <---solution???
Also I have another one:
2) 3 - |2x + 4| < 1
I'm not sure how to go about this one. Thank you for any help.
