In[1]:= DSolve[y'[x] == x (1 + y[x]^2), y[x], x]

Out[1]= {{y[x] -> Tan[(1/2)*(x^2 + 2*C[1])]}}

Same in 9.0, 7.0, and 5.2.

Maybe there was a non-printing character in your notebook between a y and a "[". Cell menu - ConvertTo - RawInputForm could help identify what went wrong, or eliminate the problem.
