Answer:

x = 0 and x = 4

Explanation:

The two terms on the right have x as a common factor, so the function can be factored as ...

y = x(x -4)

The zeros are the values of x that make y = 0, so we want the solutions to ...

0 = x(x -4)

The Zero Product Rule tells us that a product will be zero if and only if at least one factor is zero. Here, the factors are x and (x-4). They are zero when ...

x = 0 or x = 4 . . . . . the zeros of the function
