3sec^2 = 2tanx + 4 = 0.

3sec%5E2%28x%29+=+2tanx+%2B+4+=+0

3%281%2Btan%5E2%28x%29%29=2tanx+%2B4
3%281%2Btan%5E2%28x%29%29-2tanx+-4=0
3%2B3tan%5E2%28x%29-2tanx+-4=0
3tan%5E2%28x%29-2tanx+-1=0

3tan%5E2%28x%29-3tanx%2Btanx+-1=0

3tan%28x%29%28tanx-1%29%2B1%28tanx+-1%29=0
%28tanx-1%29%283tanx%2B1%29
tanx = 1 or tanx = -1/3
