What the docs are saying is that if you do something like
>>> solve(x**2 - 1, x)
Then solve
is implicitly assuming that x**2 - 1
is equal to 0
. If you wanted to solve x**2 - 1 = 2
, then you could either subtract 2
from both sides, to get
>>> solve(x**2 - 1 - 2, x)
or you could use the Eq()
class
>>> solve(Eq(x**2 - 1, 2), x)
