This is a quadratic equation with "tan(x)" as the variable. The expression does not factor; use the quadratic formula to find

tan%28x%29+=+%281%2B-sqrt%2813%29%29%2F2

Then use the inverse tangent function to find the value(s) of x.

These calculations are not ones you can do manually -- use a calculator.
