How are we supposed to know where you went wrong

if you don't tell us what you did to get the wrong answer ?

You should probably show your work. Then we can guide you on where you went wrong.

10 * sec(x)^2 + 5 * tan(x)^2 - 15 = 0

10 * (1 + tan(x)^2) + 5 * tan(x)^2 - 15 = 0

10 + 10 * tan(x)^2 + 5 * tan(x)^2 - 15 = 0

15 * tan(x)^2 - 5 = 0

3 * tan(x)^2 - 1 = 0

tan(x)^2 = 1/3

tan(x) = +/- sqrt(3)/3

So where you went wrong is that you missed 2 answers. You only gave the values from 0 to pi, rather than from 0 to 2pi.
