You can put this solution on YOUR website!
NO REAL SOLUTION.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "I did this twice now. Once numerically and once with a graph. No real solution. No point of intersection. Substitution and simplification give a quadratic in one variable, and the discriminant is negative. See both of the other posted solutions on this problem.
