You can put this solution on YOUR website!
-----------------------------------------------------
polynomial function whose zeros are x=1,-2,5,-5
-----------------------------------------------------

A polynomial function, not the only polynomial function can be
f%28x%29=%28x-1%29%28x%2B2%29%28x-5%29%28x%2B5%29, which you can fully multiply if you want.

You already know where f crosses the x-axis, because the zeros already given.
This f example bends infinitely upward to the left and infinitely upward to the right. It may appear as a curved W shape.
