**Henry**, Monday, December 6, 2010 at 11:24pmFinding 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.
