Answer:
Using Math Papa Algebra Calculator I was able to simplify to:
-81x^5+1198x^3-896x=0
In further detail this equation can be factored and then solved for the multiple x-values given, which are: x=0 or x=−3.7416573867739413 or x=3.7416573867739413 or x= -8/9 or x=8/9
Explanation:
I used a punnet square to solve for the simplified equation, from there I used Math Papa Algebra Calculator.
I would answer with the simplified answer, sorry I'd need more specifics to answer this question fully.
Once again the simplified is -81x^5+1198x^3-896x=0
