What are your thoughts? Have you got any working so far?

It may help for you to look at previous examples you may have done.

Like others have said, complete the square. Let's write it out neatly first:

x2 - 5x + 20

If you haven't learned how to complete the square yet, let me know and I'll show you how to do it.
