Write a quadratic equation that has two solution, 4 and 4. Leave the polynomial in reduced factored form.

If you know how to solve a quadratic by factoring, then you know how to do this.
Just reverse your steps
if x=4
then x4 is a factor
if x = 4
then x+4 is the second factor
so (x4)(x+4 = 0
expanded: x^2  16 = 0
