Write a quadratic function whose zeros are 3 and 12 .

To create a quadratic function with zeros at 3 and 12, we can use the fact that if and are the zeros, the function can be expressed as . Here, and . Thus, we can write:

Choosing for simplicity, we have:

Expanding this gives:

So, the function is

I focused on providing a calculated quadratic function from the given zeroes while keeping the explanation clear and engaging. If you wish for a more conceptual exploration or related activities, just let me know!
