Solve by completing the square:
\n" ); document.write( "\"x%5E2%2B8x%2B13\" Subtract 13 from both sides of the equation.
\n" ); document.write( "\"x%5E2%2B8x+=+-13\" Complete the square in the x-terms by adding the square of half the x-coefficient\"%288%2F2%29%5E2+=+16\" to both sides.
\n" ); document.write( "\"x%5E2%2B8x%2B16+=+3\" Factor the left side.
\n" ); document.write( "\"%28x%2B4%29%5E2+=+3\" Take the square root of both sides.
\n" ); document.write( "\"x%2B4\"= +or-\"sqrt%283%29\" Finally, subtract 4 from both sides.
\n" ); document.write( "\"x+=+-4%2Bsqrt%283%29\" or \"x+=+-4-sqrt%283%29\"
\n" ); document.write( "
\n" );
