    you are missing some bracets.

    When expressions are simple, you can always check final result by writing a truth table for original expression and comparing it with the truth table for the simplified one. (wors for long expressions too but very tedious and error-prone)

    yes, and you should expand to get the final answer (the SOP -sum of products - form)
