You can put this solution on YOUR website!
We'll use the formula $\"D+=+b%5E2+-+4ac\"$ . In this case, $\"a+=+k\"$ , $\"b+=+-6\"$ , $\"c+=+1\"$ and the discriminant is $\"D+=+0\"$ \r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Plug the values into the formula and solve for k.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( " $\"D+=+b%5E2+-+4ac\"$ \r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( " $\"0+=+%28-6%29%5E2+-+4%28k%29%281%29\"$ \r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( " $\"0+=+36+-+4k\"$ \r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( " $\"4k+=+36\"$ \r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( " $\"k+=+36%2F4\"$ \r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( " $\"k+=+9\"$ \r
