(x-2)^2 > 9

this inequality holds for two sets of values: x < -1 and x > 5

since we're told that x > 0, we have to go for x> 5 and therefore x > 3

does that help?

PS: I'm curious: if you were able to figure out the first, you should have no problem with the second. just have to follow the same reasoning... how come?
