Algebra.Com's Answer #291460 by Alan3354(69443)![]() ![]() You can put this solution on YOUR website! The difference of the squares of two consecutive negative odd integers is 40. Find the numbers.\r \n" ); document.write( "\n" ); document.write( "I tried to set it up like this: n=1st integer n-1=2nd integer \n" ); document.write( "n2-(n-1)2=40 (the 2's are squares, but I can't do it on my keyboard) \n" ); document.write( "but then I get stuck. \n" ); document.write( "--------------------- \n" ); document.write( "The 2nd number should be n-2, since both numbers are odd. \n" ); document.write( " \n" ); document.write( " \n" ); document.write( "4n - 4 = 40 \n" ); document.write( "4n = 44 \n" ); document.write( "n = 11 \n" ); document.write( "--> 11 & 9 \n" ); document.write( "or -11 & -9 \n" ); document.write( "------------ \n" ); document.write( "PS Use n^2 for squared, the shifted 6.\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( " \n" ); document.write( " |
