Let n = the number
\n" ); document.write( "In equation form, we have n^2 + n = 240 -> n^2 + n - 240 = 0
\n" ); document.write( "Factor:
\n" ); document.write( "(n+15)(n-16) = 0
\n" ); document.write( "This gives to possibilities: n=-15 and n=16\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "
\n" ); document.write( "
