You can put this solution on YOUR website!
Remember that quadratic equations have two solutions: The two solutions may be identical or they may be different, but there will be two of 'em.\r
\n" ); document.write( "\n" ); document.write( "\"5x%5E2+%2B+33x+-+14+=+0\" This can be factored.
\n" ); document.write( "\"%285x+-+2%29%28x+%2B+7%29+=+0\" Apply the zero products principle.
\n" ); document.write( "\"%285x+-+2%29+=+0\" or \"%28x+%2B+7%29+=+0\"\r
\n" ); document.write( "\n" ); document.write( "If \"5x+-+2+=+0\", then \"5x+=+2\" and \"x+=+2%2F5\" So, \"x+=+0.4\"
\n" ); document.write( "If \"x+%2B+7+=+0\", then \"x+=+-7\"\r
\n" ); document.write( "\n" ); document.write( "The two roots are:\r
\n" ); document.write( "\n" ); document.write( "x = 0.4
\n" ); document.write( "x = -7
\n" ); document.write( "
\n" );
