First, solve the equation:

The equation has the form:

, where a = 1, b = 4 and c =6

This problem does not have neat factors, so we apply the quadratic equation:

Using the values for a, b and c we just identified, the quadratic equation becomes:

This is a complex number! To find where this equation is less than 3 depends on what you mean by less than when talking about complex numbers.

To answer this correctly, I would ask you to verify the equation then I would ask you to define less than for complex numbers.

In any case, the roots of the equation are:
