Need help

Please, I'm new here and I need examples of five degree equations in one variable. . If possible guide me to websites that contains equations with five to n degree
Waiting your help as soon as possible, and sorry about my English.

(x - a)(x - b)(x - c)(x - d)(x - e) = 0
(Just give a, b, c, d and e constant values of your choice, and those values will be the solutions of the equation.)

Many thanks greg1313,
I don't know if I asked the right question,
What I mean is like this
a.x^n+b.x^n-1+....=0 (n=5, or n=6, or n=7.... etc)
Ex: a.x^5+b.x^4-c.x^3+....=0

I appreciate your help
I'm not looking for given solutions or lessons
All what I need a lot examples of equations five degree & above
as I mentioned. . Only examples without resolves (solutions)

Sorry again for my bad English

Why do you want examples from websites rather than examples you invent at random (most of which couldn't be solved algebraically)?

Thx skipjack
How do I invent at random!!!!?
We have to give the right values for a and b. . Etc to get =0 true
It's no matter if from websites or from here, I only need examples
True examples, how it look? Documents, links any help I will appreciate

Thx to all

Math Focus: Mainly analysis and algebra
You can create your own by expanding $$\prod_{i=1}^{5}{(x - a_i)}$$ where the $a_i$ are whatever roots you decide to select (and all will be solveable). You could even replace a pair of real roots with a quadratic having no real solutions.

Or, you can create $$\sum_{i=0}^{5}{a_i x^i}$$ to get (probably) insolvable equations.

Both are approaches that have already been suggested. Why do we have to do the (trivial) work of selecting five or six numbers for you?

Are you now saying you want examples which do have solutions, but without being told what the solutions are? If so, does it matter how many real solutions there are? For example, polynomials of odd degree must have at least one real zero, no matter what the values of the coefficients are (so you could use random values for the coefficients).
