Dale = n
\n" ); document.write( "Rosa = n - 8
\n" ); document.write( "
\n" ); document.write( "n(n - 8) = 105
\n" ); document.write( "
\n" ); document.write( "n² - 8n = 105
\n" ); document.write( "
\n" ); document.write( "n² - 8n - 105 = 0
\n" ); document.write( "
\n" ); document.write( "(n + 7)(n - 15) = 0
\n" ); document.write( "
\n" ); document.write( "n = -7, 15. Since n = -7 would make Dale's age (n) a negative number, we can eliminate this result. Therefore, we are left with n = 15.
\n" ); document.write( "
\n" ); document.write( "Dale = n = 15
\n" ); document.write( "Rosa = n - 8 = 15 - 8 = 7 \n" ); document.write( "

\n" );
