You can put this solution on YOUR website!
I'll do the first one to get you started\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "\"x=9\" or \"x=27\" Start with the given solutions.\r
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "\"x-9=0\" or \"x-27=0\" Get everything to one side so that only 0 remains on the right side (for both equations).\r
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "\"%28x-9%29%28x-27%29=0\" Use the zero product property to combine the equations.\r
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "\"x%5E2-36x%2B243=0\" FOIL out the left side.\r
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "So the answer is \"x%5E2-36x%2B243=0\"\r
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "To check your work, simply solve \"x%5E2-36x%2B243=0\" for x. Doing so will show you that the solutions are \"x=9\" or \"x=27\", which confirm the answer.
\n" ); document.write( "
\n" );
