Question

Solve (x+19)(x-12)(x+6)>0
The solution set is {x|_}

Answer 1

well, those are the roots of the polynomial, i would just test points in the intervals created by them. see where the graph is positive.

Answer 2

\[\left\{ x|x>12 \right\}\]

Answer 3

x could also be between -19 and -6.

Answer 4

so would it be {x|>12}
or all real numbers?

Answer 5

It's the union of our sets :)

Answer 6

lol yeah, its what across said :)
