Thank you all for you help
Not such good Algebra.
0.5 is a factor. It's not added or subtracted.

You start with
##s=-\frac12 at^2 ##

Multiply both sides by ##\displaystyle \ -\frac2a\ ##

You probably should take a few minutes to review basic algebra before going any further with physics. :wink:

lol, thanks guys. It's been years since I've done this kind of stuff! I've totally forgotten what to do when there's a negative number involved.

Appreciate the help @SammyS and @SteamKing

You're welcome.

It's more a matter that the numbers are all multiplied, rather than that there is a negative.
