x%5E2%2B9x%2B14%3E0

%28x%2B2%29%28x%2B7%29%3E0

The graph of the equation is a parabola that opens upward; the zeros are at -7 and -2. Therefore, the solution to the inequality is the x values for which the graph is above the x-axis: (-infinity, -7) union (-2, infinity).

A graph shows that clearly:
