You can put this solution on YOUR website!
$\"x%5E4%3C=10x%5E2-9\"$ \r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( " $\"x%5E4-10x%5E2%2B9%3C=0\"$ , from additive inverse application. You know what the basic shape will be, so just find the roots. You should check first for factorability.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( " $\"%28x%5E2-1%29%28x%5E2-9%29%3C=0\"$
\n" ); document.write( "And you can do more;
\n" ); document.write( " $\"%28x-1%29%28x%2B1%29%28x-3%29%28x%2B3%29%3C=0\"$ .\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "The ~~solution, and~~ roots, are -3, -1, 1, 3. That is \"OR\". You'll need to check the intervals carefully to know just how the graph goes around the -1 and the 1. Use arithmetic to check this as a help in making the graph.....\r
