Answer:

0.25 < x < 2

Explanation:

The quadratic can be factored as ...

4x^2 -9x +2 < 0

(4x -1)(x -2) < 0

The factors are zero for x = 1/4 and x = 2. The product of the factors will be negative, satisfying the inequality, for values of x that make one factor positive and the other one negative. Those values of x are between x=1/4 and x=2.

The solution is 1/4 < x < 2.

The graph on the number line has open circles at x=1/4 and x=2, and is shaded between those values.

_____

Additional comment

The circles on the graph are open because those x-values are not part of the solution set.
