A degree of 5, leading coefficient of two, and zero's of -2, -1, 0, 1, 5.

Well I'm not sure what to do. I think the end constant is 10, but I'm not sure what goes in between.

Okay....

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.
