You can put this solution on YOUR website!
$\"x+=+%28-b+%2B-+sqrt%28+b%5E2-4%2Aa%2Ac+%29%29%2F%282%2Aa%29+\"$ \r
\n" ); document.write( "\n" ); document.write( "If the $\"b%5E2-4ac\"$ is equal to zero then there is only one solution.\r
\n" ); document.write( "\n" ); document.write( "The general form of the quadratic is $\"ax%5E2%2Bbx%2Bc=0\"$ \r
\n" ); document.write( "\n" ); document.write( "You need to rearrange your equation to that form.\r
\n" ); document.write( "\n" ); document.write( "so $\"-16x%5E2%2B88x-121=0\"$ \r
\n" ); document.write( "\n" ); document.write( "So for your equation we have b=88 a=-16 and c=-121\r
\n" ); document.write( "\n" ); document.write( " $\"88%5E2-%284%2A-16%2A-121%29=0\"$ At this point you know there is only one solution.\r
\n" ); document.write( "\n" ); document.write( " \n" ); document.write( "
