let the number be x\r
\n" ); document.write( "\n" ); document.write( "the other number will be x-1\r
\n" ); document.write( "\n" ); document.write( "x(x-1)=90\r
\n" ); document.write( "\n" ); document.write( "x^2-x-90=0\r
\n" ); document.write( "\n" ); document.write( "x^2-10x+9x-90=0
\n" ); document.write( "x(x-10)+9(x-10)=0\r
\n" ); document.write( "\n" ); document.write( "(x-10)(x+9)=0\r
\n" ); document.write( "\n" ); document.write( "x=-9, the other number is -10\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( " \n" ); document.write( "
