If $\"x%5E2%2Bbx-20\"$ is factorable, $\"x%5E2%2Bbx-20=%28x%2Bp%29%28x-q%29=x%5E2%2B%28p-q%29x-pq\"$ ,
\n" ); document.write( "Where $\"p\"$ and $\"q\"$ are positive integers.
\n" ); document.write( "So, $\"pq=20\"$ and $\"b=p-q\"$ .
\n" ); document.write( "As $\"p\"$ and $\"q\"$ must be positive integer factors of $\"20\"$ ,
\n" ); document.write( "The maximum value of $\"b=p-q\"$ is $\"20-1=highlight%2819%29\"$ \n" ); document.write( "

\n" );
