Question 212296
I think you might want to start by clearing the fraction by multiplying both sides by 2:

2d = 2vt + at^2


Now, the only v in the problem is on the right side, so let's get rid of the at^2 by subtracting this from each side:

2d-at^2 = 2vt


Finally divide both sides by 2t to leave the v alone:

{{{(2d-at^2)/2t = (2vt)/2t}}}
{{{(2d-at^2)/2t = v}}}


That should do it!!
