To add to Gregory comment, you'll find additional tips for long
equations on following web page:

# How to break up long formulas. Breaking up overlong lines in displays
  can be very tricky, and requires a good knowledge of the underlying
  mathematics as well as a feel for good mathematical typesetting. For
  that reason, TeX doesn't break formulas, as it does with ordinary
  text. However, there are some general guidelines. Here are possible
  breaking points, in decreasing order of desirability:

    * Right before an equal sign or equivalent (e.g., a "less than"
      sign). In this case, place the alignment symbol (ampersand) placed
      before the equal sign, i.e., ... + x \\ &= . The equal signs (or
      equivalent) should be aligned.

    * Before a plus or minus sign. In that case, the continuation line
      should be shifted to the right by a \qquad. If the continuation
      line is very short, two \qquad's might be better.

    * Between two large "chunks" that are multiplied. The chunks could
      be large parenthesized expression, sums or integrals. This should
      be used only as a last resort, and in that case the preceding line
      should end with an explicit multiplication symbol (\times), the
      continuation line should begin with \times symbol and be shifted
      as far to the right (by preceding it with a few \qquad's after the
      alignment symbol).


Yours,
d.
