student opens math book two facing pages the product is 1980 what is the first page and the second page?
\n" ); document.write( "------------------------
\n" ); document.write( "There are 2 ways to do this:
\n" ); document.write( "#1, the hard way.
\n" ); document.write( "n*(n+1) = 1980
\n" ); document.write( "\"n%5E2+%2B+n+-+1980+=+0\"
\n" ); document.write( "(n+45)*(n-44) = 0
\n" ); document.write( "n = 44
\n" ); document.write( "n = -45
\n" ); document.write( "Not many books have negative page #s, so it's 44 and 45.
\n" ); document.write( "-------------------
\n" ); document.write( "#2, the easy way.
\n" ); document.write( "Since the numbers differ by only 1, the square root of 1980 will be between the 2.
\n" ); document.write( "\"sqrt%281980%29+=+44.497...\"
\n" ); document.write( "It's 44 and 45.
\n" ); document.write( " \n" ); document.write( "
