"Take something into account" vs "Take into account something" — are both correct?

Solution 1:

"Take X into account" generally works better when X is not a lengthy expression. "Take into account X" generally works better when X is long enough that the reader might have lost the sense of "take" by the time "into account" rolls around. The less experienced the likely reader, the shorter the maximum length of X before it ought to appear after "into account" rather than before. The same is true of other idiomatic expressions constructed this way.
