Set this up as if it were an equation, and find the roots.
5n^2 – 19n – 4 >= 0
The roots are -.2 and 4. The only question is whether the solution set lies inside the parabola or outside.
To check, choose a value for n that is between -.2 and 4 and substitute it into the inequality to see if you get a true statement. To make it easy, let’s use zero.
we then get the statement 0 >= 4, which is not true, so the solution set is the area outside the parabola, which translates to n <= -.2 or n >= 4
