Let x be the number. You are told
\n" ); document.write( " $\"%28x%2Ax%29+-+%28x%2Bx%29+=+99\"$
\n" ); document.write( " $\"x%5E2+-+2x+=+99\"$
\n" ); document.write( " $\"x%5E2+-2x+-+99+=+0\"$
\n" ); document.write( " $\"%28x-11%29%28x%2B9%29+=+0\"$
\n" ); document.write( "So either $\"x-11+=0\"$ or $\"x%2B9+=+0\"$
\n" ); document.write( "Thus x is either 11 or -9\r
\n" ); document.write( "\n" ); document.write( "Check your answers.
\n" ); document.write( "Is 11^2 - 22 = 99??
\n" ); document.write( "is 121-22 = 99 ??
\n" ); document.write( "Is (-9)^2 - (-18) = 99
\n" ); document.write( "Does 81 + 18 = 99?? \n" ); document.write( "
