Hi there,
\n" ); document.write( "Make the two consecutive
\n" ); document.write( "integers be n + 1, n + 3
\n" ); document.write( "(n + 1)(n + 3) = 2(n + 3) + 60
\n" ); document.write( "Multiply out
\n" ); document.write( "n^2 + 4n + 3 = 2n + 6 + 60
\n" ); document.write( "Collect like terms and put in form
\n" ); document.write( "ax^2 + bx + c = 0
\n" ); document.write( "n^2 + 2n - 63 = 0
\n" ); document.write( "Factorise
\n" ); document.write( "(n - 7)(n + 9) = 0
\n" ); document.write( "n + 9 = 0
\n" ); document.write( "n = -9 (no answer as -ve)
\n" ); document.write( "n - 7 = 0
\n" ); document.write( "n = 7
\n" ); document.write( "Two numbers are. 8 and 10
\n" ); document.write( "hope this helps:-) \n" ); document.write( "
\n" );
