**Calculus (Optimization, Still Need Help)**

I just wanted to correct something for my equation, it should be: V = (14 - 2x)(8 - 3x)(x), which simplifies to V = 112x - 44x^2 - 4x^3. Take the derivative: V' = 112 - 88x - 12x^2 Now all I need are the roots, any help? I think I found one around 1.10594, possibly?

Still doesn't explain where the v^5/2 came from. I don't see any v terms anywhere above there. hat is F(v) really? If it involves v^3/2, then unless you get rid of the parentheses, you will need to use the quotient rule.
