let the integer be x \r
\n" ); document.write( "\n" ); document.write( "given x+x^2=72\r
\n" ); document.write( "\n" ); document.write( " => x(x+1)=72\r
\n" ); document.write( "\n" ); document.write( "since x is an integer the only possible value of x is 8\r
\n" ); document.write( "\n" ); document.write( " 8*9=72\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "so answer is 8
