The product of the page numbers is 1806, find the pages numbers. \n" ); document.write( "First page__________ \n" ); document.write( "Second page_________ \n" ); document.write( "How do I work this problem? \n" ); document.write( "-------------------- \n" ); document.write( "The quickest and easiest way is to find the sqrt(1806) \n" ); document.write( "= ~ 42.49 \n" ); document.write( "That's between the 2 numbers, so they're 42 and 43. \n" ); document.write( "----------------- \n" ); document.write( "The hard way: \n" ); document.write( "n*(n+1) = 1806 \n" ); document.write( "n^2 + n - 1806 = 0 \n" ); document.write( "(n-42)*(n+43) = 0 \n" ); document.write( "n = 42 \n" ); document.write( " \n" ); document.write( " |
