    Are you familiar with boolean algebra? Do you know how to make a blank truth table?
    To make the truth table, make all the operations in your expression until you have a sum of terms. These will tell you wich spots of the table you should fill.
    As for the circuit, that's simpler. An addition corresponds to an OR gate. Multiplication to an AND and complement to a NOT. Make them in the order you have them in your original expression.
