You can put this solution on YOUR website!
y= ln(x^2-1x-6)
\n" ); document.write( "----
\n" ); document.write( "You can only find the ln of a positive number.
\n" ); document.write( "---
\n" ); document.write( "Solve x^2-x-6 > 0
\n" ); document.write( "Factor:
\n" ); document.write( "(x-3)(x+2)> 0
\n" ); document.write( "---

\n" ); document.write( "---
\n" ); document.write( "Test a value from each of the line intervals
\n" ); document.write( "in the inequality to see where solutions lie.
\n" ); document.write( "---
\n" ); document.write( "Note: You need only test the signs since you are comparing to zero.
\n" ); document.write( "---
\n" ); document.write( "If x = -10 you get -*- > 0 ; true so solutions in (-inf,-2)
\n" ); document.write( "---
\n" ); document.write( "If x = 0 you get -*+ > 0 ; false
\n" ); document.write( "----
\n" ); document.write( "If x = 10 you get +*+ > 0; true so solutions in (3,+inf)
\n" ); document.write( "====
