(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

Determine the equation in simplied form for the family of quartic functions with zeroes of..

5 (order 2) and -1± 2√ 2

2. Relevant equations

3. The attempt at a solution

so.. (x-5)^2 (x-1+2√2) (x-1-2√2)

(x-5) (x-5) (x-1+2√2) (x-1-2√2)

Would be all of it expanded, but I dont know how to foil on this.. theres 2 terms on the left side brackets and 3 terms on the right side brackets.. (x) (-1) (2√2) , I know that X will become x^4, but i dont get how to continue using foil, can anyone explain?

We never learned this.. so.. i also know that the plusminus root is (x+1)^2 + 8 if simplified into that form..
