If I rewrite an equation

$\sqrt{a} + b = 10$

to

$a = 100 - 20b + b^2,$

how would I call that transformation to explicitly express $a$?

    One could also say you're *isolating* $a$.2012-07-27

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'?

    'isolating' was already suggested in t$h$e comments.2013-02-14
