Product Description
Too many students end their study of mathematics before ever taking an algebra course. Others attempt to study algebra, but are unprepared and cannot keep up. Key to Algebra was developed with the belief that anyone can learn basic algebra if the subject is presented in a friendly, non-threatening manner and someone is available to help when needed. Some teachers find that their students benefit by working through these books before enrolling in a regular algebra course--thus greatly enhancing their chances of success. Others use Key to Algebra as the basic text for an individualized algebra course, while still others use it as a supplement to their regular hardbound text. Allow students to work at their own pace. The Key to Algebra books are informal and self-directing. Book 10 covers Square Roots and Quadratic Equations.Format: PaperbackPublisher: Key Curriculum Press ... Read more

Excerpt: In algebra, the partial fraction decomposition or partial fraction expansion is used to reduce the degree of either the numerator or the denominator of a rational function. The outcome of a full partial fraction expansion expresses that function as a sum of fractions, where: In symbols, one can use partial fraction expansion to change a rational function in the form where and g are polynomials, into a function of the form where hn are polynomials that are factors of g(x), and are in general of lower degree. The full decomposition pushes the reduction as far as it will go: in other words, the factorization of g is used as much as possible. To decrease the degree of the numerator directly, the Euclidean algorithm can be used, but in fact if f already has lower degree than g this isn't helpful. Thus the partial fraction decomposition may be seen as the inverse procedure of the more elementary operation of addition...More: http://booksllc.net/?id=247288 ... Read more
