0 = 400 - 600t^2

transpose for t

I get t = -400/-600^2

I am not confident that this right, please advise?

No, it's not correct. You really should simplify each step before taking on any other step... E.g. $\displaystyle \displaystyle \frac{-400}{-600} = \frac{2}{3}$...

Also, to undo squaring, you don't square both sides. You take the square root of both sides. - Feb 23rd 2011, 08:30 AMjohn1875
Wonder if you could clarify this point? Would I √(2/3) or √2 /3 ?

It's $\displaystyle \displaystyle \sqrt{\frac{2}{3}}$.
