Well I'm not sure what to do. I think the end constant is 10, but I'm not sure what goes in between. __________________ C://dos C://dos.run run.dos.run

Here's a hint: If I wanted to write a polynomial of degree 2, with leading coefficient 3, that has zeros at 4 and -9, I would do this: 3(x - 4)(x + 9) then expand.

REALLY good hint!

So i'd set up 3x(x+2)(x+1)(x-1)(x-5) and expand. Y'all can do the fun part.
