transposition of formula K SUBJECT

X=kgt2
2u(1+k)
make k the subject
(top 2 meaning sqaured)

Do you mean this?

$ x = \frac {kgt^2} {2u(1+k)} $

If so, you can multiply through by 2u(1+k) to get:

$ 2u(1+k)x = kgt^2 \\ 2ux+2ukx = kgt^2 \\ 2ux = kgt^2 - 2ukx = k(gt^2 - 2ux) \\ k = \frac {2ux} {gt^2 - 2ux} $
