Algebra.Com's Answer #105486 by nabla(475)![]() ![]() ![]() You can put this solution on YOUR website! let the numbers be: 2n+1, 2n+3\r \n" ); document.write( "\n" ); document.write( "Then, (2n+1)(2n+3)=143 \n" ); document.write( "4n^2+8n+3=143 \n" ); document.write( "4n^2+8n-140=0 \n" ); document.write( "n^2+2n-35=0 \n" ); document.write( "(n+7)(n-5)=0\r \n" ); document.write( "\n" ); document.write( "So n=-7 or n=5. Now, we probably only want the positive solution here, so n=5.\r \n" ); document.write( "\n" ); document.write( "And the numbers are: \n" ); document.write( "11 and 13.\r \n" ); document.write( "\n" ); document.write( "11*13=143. \n" ); document.write( " |
