Thank you for all the help. I got mathematica the other day and just got the answer after playing around with it a little bit.

I'm not really sure how to simplify the radical because it's inside the parenthesis. I doubt it's as simple as this: \frac{36/64.4} {1/2 + (2 + x)} = {x}(1 - x^2/4) Sorry that the parenthesis aren't closed I'm still trying to get used to posting here.

It's actually this: \frac{36}{64.4(1/2 + (2 + x)\sqrt{1 - x^2/4}} ) - {x}{\sqrt{1 - x^2/4}} = 0

Actually I think I'm wrong. I think I could get it if someone could square the following expression for me: 64.64 * [0.5 + (2 + x) * (Sqrt[1 - (0.25*x^2)])] I just can't get it no matter what I try.

I just need to simplify first then I have to solve for x. I got the following once I factored everything out and simplified things: (259*x^8)+(1037*x^7)-(1037*x^6)-(8294*x^5)-(4406*x^4)+(16589*x^3)+(17626*x^2)

I need the following expression simplified. 36/[64.4*(0.5+(2+ x)*((1-(1/4)*x^2 )^0.5)) ]-x*((1-(1/4)*x^2 )^0.5)=0
