If one of the roots of the equation $\"+x%5E2%2Bkx=6+\"$ is $\"2\"$ , means $\"x=2\"$ \r
\n" ); document.write( "\n" ); document.write( "plug it in $\"+x%5E2%2Bkx=6+\"$ and find the value of $\"k\"$ \r
\n" ); document.write( "\n" ); document.write( " $\"+2%5E2%2Bk%2A2=6+\"$ \r
\n" ); document.write( "\n" ); document.write( " $\"+4%2B2k=6+\"$ \r
\n" ); document.write( "\n" ); document.write( " $\"+2k=6-4+\"$ \r
\n" ); document.write( "\n" ); document.write( " $\"+2k=2+\"$ \r
\n" ); document.write( "\n" ); document.write( " $\"+highlight%28k=1%29+\"$ \r
\n" ); document.write( "\n" ); document.write( "so, your equation is: $\"+x%5E2%2Bx=6+\"$ \r

\n" ); document.write( "\n" ); document.write( "as you can see from the graph, one root is $\"2\"$ and other one is $\"-3\"$ \r
