list all roots of
1) x^53x^4+3x^3x^2=0
2)8x^312x^2+6x1
3) x^4=16

Sorry, I don't remember how to do #1 and 2, but 3 is x=+2

Finding roots of Eqs that are 3rd degree or higher is done mostly by trial and error.However, Excel Spread sheets made the task a little easier.
First, we find a number that will satisfy the given Eq. It was determined
that 0 and 1 were the only numbers that
satisfied your Eq. so the roots are:
1. x = 0, and x = 1.
2. I found only one root for this one:
X = 0.50.
3. X^4 = 16.
Take sqrt of both sides:
X^2 = 4,
Take sqrt of both sides and get:
x = + 2.
