whats the typo?

I'm trying to use this y = R (the radius of the earth) +h ( the height i want to reach).

i was working on a differential equation to find the initial velocity of a rocket to get to height h. so i have, which i got and its correct cause its the solution in the book, v^2 = 2g(R/(R+h))-2gR+V(0)^2 v = velocity g = acceleration of gravity at Earth's surface R= radius of earth h...
