Simplify expression with root
The result of some integral, computed using integrate(), is:
2*(2378*sqrt(2) - 3363)/(408*sqrt(2) - 577)
However, when I do the integral "by hand" I get
2*(3-2*sqrt(2))
Numerically both results are the same, but the first result is a lot more complicated.
Multiplying separately the numerator and denominator of the first expression by (408*sqrt(2) + 577) brings the correct result.
What can I do to simplify the first expression and get something really simple, as the second one?
Thanks in advance!
