Itz actually a physics 4mula, i just changed the letters so that one might not notice cuz itz very common. Your answer would've been right if the '2' meant 'x2', it actually means 'raised to the pwr of 2'.....sorry, my mistake

Is this the formula?

x = (y * z) + (y * z^2)/2

z= -1+sqrt[1+(2x/y)], and z= z= -1-sqrt[1+(2x/y)]

The closest physics formula I can find is s = vt + at2/2 but v <> a so how can they both be y?

I insist? Normally I do not insist. As for this one... it seemed not to be actual homework. I choose this time to believe he was checking his work.

And if he actually lied then I figure class will get quite a bit interesting if he doesn't actually learn how to work with equations.
