Given two form $omega$, find $mu$ such that $dmu=omega$? [duplicate]

This question already has an answer here:
Does there exist a $1$-form $alpha$ with $dalpha = omega$?
2 answers
I am reading a textbook on differential forms and there is a question of the form: given a $k$-form, $omega$, on say $mathbb{R^3}$, find $mu$ such that $dmu=omega$. For example, if $omega= (x_{1}^2 +x_{2}^2)dx_1 wedge dx_2$, what is $mu$?
I am looking for a systematic method to solve these types of questions.
Thanks

$dmu=omega$ implies that $d^2mu=domega=0$. The Poincare Lemma implies that $omega$ is exact, if you look at a standard proof of this lemma, it constructs $mu$ such that $dmu=omega$ given a closed form $omega$.
