Question 93220: hi there,
I am trying to simplify the following expression
s=u.(v-u)/a + 1/2a((v-u)/a)^2
it should end up as v^2=u^2+2as
please help beacuse I cant seam to get it to come out, I have expanded the brackets but still no joy.

Question 93260: hi there,
I asked the following question before and I had a solution given to me, I do not understand some of it though, some guidance would be great.
s=u.(v-u)/a + 1/2a((v-u)/a)^2
it should end up as v^2=u^2+2as
first step was to multiply by 2a giving....
2as=2u(v-u)+(v-u)^2
expanding
2as= 2uv-2u^2+v^2-2vu+u^2
apparently by collecting terms this is equal to 2as=v^2-u^2, could someone please explain this last step for me
