Make A the subject of the following formula: S = UT + 1/2AT^2

The important thing to remember when rearranging equations is whatever you do to one side must be balanced with the other.1) So in this case, the first thing we want to do is to leave the term with A in it (1/2AT2) on its own, and so to do that we want to subtract UT from both sides leaving S-UT = 1/2AT2 2) Next thing we want to do to is to make sure that both sides are working with whole numbers so let’s multiply both sides by 2 to get rid of that pesky 1/2.2(S-UT) = AT23) NEARLY THERE. The final thing to do now is to get A on its own and to do that we must divide both sides by T2. And our answer is:A = 2(S-UT)/T2
