You can put this solution on YOUR website!

2sec%5E2%28x%29-3sec%5E%22%22%28x%29-2=0

%282sec%5E%22%22%28x%29%5E%22%22%2B1%29%28sec%5E%22%22%28x%29%5E%22%22-2%29=0

   

The reason there is no solution to the first part, but there is to
the second part is because all secants and cosecants are greater than
1 in absolute value.
