You can put this solution on YOUR website!
I did this FAST and did not check carefully.
\n" ); document.write( "Look at critical values.
\n" ); document.write( "neg infinity to -4
\n" ); document.write( "-4 to 7/3
\n" ); document.write( "7/3 yo 7
\n" ); document.write( "7 to pos infinity\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "x=-1/2, and or x=-5/2.
\n" ); document.write( "The other two intervals seem to have no solutions.
\n" ); document.write( "
\n" );
