If I rewrite an equation
$\sqrt{a} + b = 10$
to
$a = 100 - 20b + b^2,$
how would I call that transformation to explicitly express $a$?

Reposting my comment on the OP's request:
Is "solving for $a$ and expanding the square using the binomial formula" precise enough for your needs?
What about 'isolating'? Or 'extricating'?
