You can put this solution on YOUR website!
it's a \"quadratic\", to solve move everything to one side:
\n" ); document.write( "a^2=-27-12a
\n" ); document.write( "a^2+12a=-27
\n" ); document.write( "a^2+12a+27=0
\n" ); document.write( "factor the left:
\n" ); document.write( "(a+3)(a+9) = 0
\n" ); document.write( "a = {-3, -9}\r
\n" ); document.write( "\n" ); document.write( " \n" ); document.write( "

\n" );
