Answer:
(-3,0), (1,0), (2,0), (-2,0)
Explanation:
A zero is any place that the function (output) is equal to zero. Since the different sets of paranthesis are being multiplied together, if just one of them is equal to zero, the entire function is equal to zero. This means that when you set each set of paranthesis equal to zero (ex. for the first one: x+3 = 0), you get the x value at which the function is equal to zero.
