Of course you have to rearrange it
X -Xo = (V-Vo)(V+Vo)/2a (X-Xo)2a = (V-Vo)(V+Vo) 2 a (X-Xo) = V^2-Vo^2 ok to go from the first

You want to show that
V^2 - Vo^2 = 2 a (X - Xo) first rewrite that as: (V-Vo)(V+Vo) = 2a (X-Xo) now your average velocity during

I'm trying to derive the formula
v^2 = v0^2 + 2a(x-x0) were zeros are subscripts my book tells me to derive it this way use the

oh... Xo is not zero
thanks
This is what i did x = 2^-1(v0 + v)a^-1(v-v0) + x0 simplfy x = (a2)^-1(v^2 -v0^2)+ x0 (x = (a2)^-1(v^2 -v0^2)+ x0)2a (2a)x = (v^2-v0^2) + x0 (2a)x - x0 = (v^2-v0^2) + x0 - x0 (2a)x - x0 + v0^2= (v^2 - v0^2) + v0^2 (2a)x - x0 + v0^2 = v^2 i do not see were
