x=ks^2/t
when s is doubled it will be 4 times
when both are doubled it will be two times

The first two people forgot about the cases where s and t are less than one. The square of any number less than one is smaller than the given number, and the inverse of a positive number less than one is greater than one.

X = k*S^2/T
when S is doubled,... the value of X becomes
k*(2S)^2/t = 4kS^2/t
4 times what it once was
when both S & T are doubled
X=4kS^2/2t => 2kS^2/t
the value is 2times what it once was.
