If you start with what you're given 5x2 + 19x + 16 > 20
Subtract 20 from both sides 5x2 + 19x – 4 > 0
Factor the left side (5x – 1)(x + 4) > 0
I thought I I'd figure out the answer as I went,
but I find that I don't know what to do now.

Between x = -4 and + 1/5 the graph is neg or zero
Below -4 or above +1/5 it is > 0
so (-inf,-4) U (1/5, + inf) it is greater than zero (or the original equation is > 20)
EDIT: So NOT satisfied would be [-4,1/5] -4, -3,-2,-1 0 FIVE integer values
