Solve for x???
\n" ); document.write( "\"sqrt%28x-1%29%2Bx+=+7\" Subtract x from both sides.
\n" ); document.write( "\"sqrt%28x-1%29+=+7-x\" Square both sides.
\n" ); document.write( "\"x-1+=+49-14x%2Bx%5E2\" Add 1 to both sides.
\n" ); document.write( "\"x+=+50-14x%2Bx%5E2\" Subtract x from both sides.
\n" ); document.write( "\"0+=+50-15x%2Bx%5E2\" Rearrange into standard form.
\n" ); document.write( "\"x%5E2-15x%2B50+=+0\" Factor.
\n" ); document.write( "\"%28x-10%29%28x-5%29+=+0\" Apply the zero product rule.
\n" ); document.write( "\"x-10+=+0\" or \"x-5+=+0\" so...
\n" ); document.write( "\"x+=+10\" or \"x+=+5\"
\n" ); document.write( "
\n" );
