You can put this solution on YOUR website!
m^2 -24m -81 = 0
\n" ); document.write( ".
\n" ); document.write( "You need to look at factors of 81 that are 24 apart.
\n" ); document.write( "Otherwise you will have to use the quadratic equation.
\n" ); document.write( ".
\n" ); document.write( "3 * 27 = 81
\n" ); document.write( "and
\n" ); document.write( "27 - 3 = 24
\n" ); document.write( "so
\n" ); document.write( "you can factor it
\n" ); document.write( ".
\n" ); document.write( "(m - 27)(m + 3) = 0
\n" ); document.write( ".
\n" ); document.write( "Use FOIL to check
\n" ); document.write( ".
\n" ); document.write( "m^2 +3m -27m -81 = 0
\n" ); document.write( ".
\n" ); document.write( "m^2 -24m -81 = 0
\n" ); document.write( ".
\n" ); document.write( "Done. \n" ); document.write( "

\n" );
