Solve: \"x%5E2%2B2x+=++8\" by completing the square.
\n" ); document.write( "\"x%5E2%2B2x=+8\" Add the square of half the x-coefficient. \"%282%2F2%29%5E2+=+1\"
\n" ); document.write( "to both sides.
\n" ); document.write( "\"x%5E2%2B2x%2B1+=+8%2B1\" Factor the left side.
\n" ); document.write( "\"%28x%2B1%29%5E2+=+9\" Take the square root of both sides.
\n" ); document.write( "\"x%2B1+=+3\" or \"x%2B1+=+-3\" Subtract 1 from both sides in each solution.
\n" ); document.write( "\"highlight%28x+=+2%29\" or \"highlight%28x+=+-4%29\"
\n" ); document.write( "
\n" );
