Question: Consider the equation xy = 0. In this equation, two variables are multiplied and the result is 0. Can the equation be true if neither

Consider the equation xy = 0. In this equation, two variables are multiplied and the result is 0. Can the equation be true if neither variable is equal to 0? Can the equation be true if only one variable is equal to 0? If so, which one needs to be equal to 0? Can the equation be true if both variables are equal to 0?

What process could you use to solve equations of the form (x + a)(x + b) = 0? In this case there are only two factors (values being multiplied) that are being set equal to 0. How would you solve the equation if there were more than two factors? Explain.
