You can put this solution on YOUR website!
Notice that $\"+%28-5%29%2A%28-9%29+=+45+\"$
\n" ); document.write( "and also $\"++5+%2B+9+=+14+\"$
\n" ); document.write( "In a quadratic equation, you have
\n" ); document.write( " $\"+%28+n+-+k+%29%2A%28+n+-+j+%29+=+n%5E2+-+%28+j+%2B+k+%29%2An+%2B+j%2Ak+=+0+\"$
\n" ); document.write( "In your case,
\n" ); document.write( " $\"+j+=+5+\"$
\n" ); document.write( " $\"+k+=+9+\"$ , so
