Получена теорема о разложении многочлена с коэффициентами в произвольном кольце с делением. Показано, что если нецентральный элемент не является корнем многочлена над произвольным кольцом с делением, то в классе сопряженности этого элемента бесконечно много элементов, не являющихся корнями этого многочлена. Также в работе получены оценки для количества различных классов сопряженности сферических корней для некоторых типов многочленов над алгебрами кватернионов.</p></abstract><trans-abstract xml:lang="en"><p>We consider properties of polynomials with coefficients in division rings. A theorem on the decomposition of a polynomial with coefficients in an arbitrary division ring is obtained. It is shown that if a non-central element is not a root of a polynomial over an arbitrary division ring, then the conjugacy class of this element contains infinitely many elements that are not roots of this polynomial. The paper also contains estimates for the number of different conjugacy classes of spherical roots for some types of polynomials over quaternion algebras.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>кольцо с делением</kwd><kwd>корень (правый) многочлена</kwd><kwd>алгебра обобщенных кватернионов</kwd><kwd>класс сопряженности элемента</kwd><kwd>сферический корень</kwd></kwd-group><kwd-group xml:lang="en"><kwd>division ring</kwd><kwd>(right) root of a polynomial</kwd><kwd>algebra of generalized quaternions</kwd><kwd>conjugacy class of an element</kwd><kwd>spherical root</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Работа выполнена в рамках НИР «Разработка алгебро-геометрических и представленческих методов исследования конечнопорожденных групп, конечномерных алгебр и квадратичных форм», государственной программы научных исследований «Конвергенция–2025», № ГР 20212390</funding-statement></funding-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Ore O.
