$\"x%5E2-6x-16=0\"$
\n" ); document.write( "

\n" ); document.write( "Plus = P
\n" ); document.write( "Multiplication = M
\n" ); document.write( "

\n" ); document.write( "Every quadract equation is = x^2-Px+M=0
\n" ); document.write( "

\n" ); document.write( " $\"P+=-b%2Fa+\"$ and $\"M+=+c%2Fa\"$
\n" ); document.write( "

\n" ); document.write( " $\"x%5E2-6x-16=0\"$

$\"a=1\"$ , $\"b=-6\"$ and $\"c=-16\"$

\n" ); document.write( " $\"P=-%28-6%29%2F1\"$ --> $\"P=6\"$ and $\"M=-16%2F1\"$ --> $\"M=-16\"$
\n" ); document.write( "

\n" ); document.write( " $\"x%5E2-Px%2BM=0\"$ is $\"x%5E2-%286%29x%2B%28-16%29=0\"$
\n" ); document.write( "

\n" ); document.write( "What numbers have the $\"plus=6\"$ and $\"multiplication=-16\"$ ?
\n" ); document.write( "Answer: $\"-2\"$ and $\"8\"$
\n" ); document.write( "

\n" ); document.write( "The factor of $\"x%5E2-6x-16=0\"$ is $\"highlight%28%28x-8%29%28x%2B2%29=0%29\"$ \r
