Would you please give one or two (or more, sorry hehehe) to help me?(adsbygoogle = window.adsbygoogle || []).push({});

How can you make up a polynomial that:

- crosses the x-axis at -2

- just touches the x-axis at 1 ("touch" as the graph y=x^2 would only touch, not cross, the x-axis)

- and is above the x-axis between -2 and 1.

I know there must be equations that are not cubic that satisfy these conditions. Oh and the graph contains no additional contact with the x-axis. How would you create the equation? Please help^^
