Question about how to re-arrange a complicated formula.

re-arranging s=vt - 0.5*at^2 to make T the subject @Engineering

Answer 1

at^2 -2vt +2s = 0

Answer 2

I just don't understand how to get there

Answer 3

s=vt - 0.5*at^2

s= vt -1/2(at²)

-at²/2+vt-s=0

(-a*t²)/2+v*t-s=0

Answer 4

thnak you very much
do you have any general tips on re-arranging formulae? i know you do the opposite to what you have, but what about the order?

Answer 5

Just try to put it under the following form:
\[ax^{2} +bx + c =0\]or
\[ax^{n} +bx^{n-1}+ ... + yx+z=0\]and review the steps a followed in my first post.

Answer 6

thank you very much
