The Rational Zero Test and Finding Real
Zeros
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).
A.APR.3
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.
A.APR.6
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.
