Hi, welcome to the forum

We have an excellent tutorial showing how to find the roots of a quantic (5th degree polynomial). Would you be comfortable copying its solution? If you'd like a fresh solution, let me know...

The second question is also quite simple.

Use the formula found in this video from our channel:



And just select n values greater than r. If you need further clarification, reply back, but make sure you watch the video

This one is extremely easy if you put the polynomials in factored form:

Example:

(x - a)(x - b)(x - c)(x - d)(x - e) = y

Set a, b, c, d, and e to any number(s) you like. You may also change negative to positive:

(x + a)(x + b)(x + c)(x + d)(x + e) = y


(x - 1)(x - 2)(x - 3)(x - 4)(x - 5) = y

r≤n means that n is bigger than r.



Ex. 1 (n=6, p=5)
\(\frac{6!}{\left(6-5\right)!}=\frac{6\times 5\times 4\times 3\times 2\times 1}{\left(1\right)!}=720\)

Ex. 2 (n=7, p=5)
\(\frac{7!}{\left(7-5\right)!}=\frac{7\times 6\times 5\times 4\times 3\times 2\times 1}{2\times 1}=2520\)

Ex. 3 (n=8, p=4)
\(\frac{8!}{\left(8-4\right)!}=\frac{8!}{4!}=\frac{8\times 7\times 6\times 5\times 4\times 3\times 2\times 1}{4\times 3\times 2\times 1}=1680\)
