Apply to polynomial and rational expressions in the context of Algebra II.→NY-A.SSE.4Derive the formula for the sum of a finite geometric series and use the formula to solve problems.→NY-A.APR.2Know and apply the Remainder Theorem: for a polynomial p(x) and a number a the remainder on division by x - a is p(a). If p(a) = 0 then (x - a) is a factor of p(x).→NY-A.APR.3Identify zeros of polynomials when suitable factorizations are available and use the zeros to construct a rough graph of the function defined by the polynomial.→
