Starting with n^2 - 6n = - 8,
\n" ); document.write( "Set the equation equal to 0
\n" ); document.write( "n^2 - 6n + 8 = -8 + 8
\n" ); document.write( "n^2 - 6n + 8 = 0\r
\n" ); document.write( "\n" ); document.write( "Solve the quadratic by finding multiples of 8 which add to -6
\n" ); document.write( "4 and 2 work: 4*2=8
\n" ); document.write( "Both must be negative to get -6, where -4 + - 2 = -6
\n" ); document.write( "It works because -4*-2=8\r
\n" ); document.write( "\n" ); document.write( "So,
\n" ); document.write( "(n - 4)(n - 2)\r
\n" ); document.write( "\n" ); document.write( "Therefore,
\n" ); document.write( "n-4=0
\n" ); document.write( "n - 4 + 4 = 0 + 4
\n" ); document.write( "n = 4
\n" ); document.write( "n - 2 = 0
\n" ); document.write( "n - 2 + 2 = 0 + 2
\n" ); document.write( "n = 2\r
\n" ); document.write( "\n" ); document.write( "Ultimately,
\n" ); document.write( "n = 4 and n = 2
\n" ); document.write( " \n" ); document.write( "
\n" );
