You can put this solution on YOUR website!
Let x be the side of the square.
\n" ); document.write( "\"x%5E2=A\" and A is not given but expected to be a constant.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "The dimensions of the rectangle: \"x%2B8\" and \"x-4\".\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Same areas, so \"%28x%2B8%29%28x-4%29=A\".\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "The situation is of two expressions for the same area A.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "\"highlight_green%28%28x%2B8%29%28x-4%29=x%5E2%29\"
\n" ); document.write( "You do the rest. Any difficulty?
\n" ); document.write( "(Could be solved in three steps, maybe four).\r

\n" ); document.write( "\n" ); document.write( "x=8
\n" ); document.write( "
\n" );
