# Algebra: Arithmetic with Polynomials and Rational Expressions722 preguntas44 habilidades

## HSA-APR.A.1

345 preguntas21 habilidades
Understand that polynomials form a system analogous to the integers, namely, they are closed under the operations of addition, subtraction, and multiplication; add, subtract, and multiply polynomials.

## HSA-APR.B.2

27 preguntas2 habilidades
Know and apply the Remainder Theorem: For a polynomial p(x) and a number a, the remainder on division by x – a is p(a), so p(a) = 0 if and only if (x – a) is a factor of p(x).

## HSA-APR.B.3

40 preguntas3 habilidades
Identify zeros of polynomials when suitable factorizations are available, and use the zeros to construct a rough graph of the function defined by the polynomial.

## HSA-APR.C.4

20 preguntas1 habilidad
Prove polynomial identities and use them to describe numerical relationships.

## HSA-APR.C.5

16 preguntas1 habilidad
Know and apply the Binomial Theorem for the expansion of (x + y)n in powers of x and y for a positive integer n, where x and y are any numbers, with coefficients determined for example by Pascal’s Triangle.

## HSA-APR.D.6

116 preguntas8 habilidades
Rewrite simple rational expressions in different forms; write a(x)/b(x) in the form q(x) + r(x)/b(x), where a(x), b(x), q(x), and r(x) are polynomials with the degree of r(x) less than the degree of b(x), using inspection, long division, or, for the more complicated examples, a computer algebra system.

## HSA-APR.D.7

158 preguntas8 habilidades
Understand that rational expressions form a system analogous to the rational numbers, closed under addition, subtraction, multiplication, and division by a nonzero rational expression; add, subtract, multiply, and divide rational expressions.
