Domain - Seeing Structure in Expressions
Cluster - Interpret the structure of quadratic and exponential expressions.
[MII.A-SSE.A.2] - Use the structure of an expression to identify ways to rewrite it. For example, see (x + 2)2 – 9 as a difference of squares that can be factored as ((x + 2) + 3)((x + 2) – 3).
- Expression
A mathematical phrase that combines operations, numbers, and/or variables (e.g., 32 ÷ a).
[MII.A-SSE.B.3.a] -
Factor a quadratic expression to reveal the zeros of the function it defines.
[MII.A-SSE.B.3.c] -
Use the properties of exponents to transform expressions for exponential functions. For example, the expression 1.15t can be rewritten as (1.15 1/12)12t ≈ 1.01212t to reveal the approximate equivalent monthly interest rate if the annual rate is 15%.
[MIII.N-CN.C.8] -
(+) Extend polynomial identities to the complex numbers. For example, rewrite x2 + 4 as (x + 2i)(x – 2i).
[MIII.A-SSE.B.4] -
Derive the formula for the sum of a finite geometric series (when the common ratio is not 1), and use the formula to solve problems.* For example, calculate mortgage payments.
[MIII.A-APR.B.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.
[MIII.A-APR.C.4] -
Provide polynomial identities and use them to describe numerical relationships. For example, the polynomial identity (x2 + y2)2 = (x2 – y2)2 + (2xy)2 can be used to generate Pythagorean triples.
[MIII.A-APR.C.5] -
(+) 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.
[MIII.A-APR.D.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.
[MIII.A-APR.D.7] -
(+) 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.
[PC.N-CN.C.8] -
(+) Extend polynomial identities to the complex numbers. For example, rewrite x2 + 4 as (x + 2i)(x – 2i).
[PC.A-APR.C.5] -

[AQR.A-APR.C.5] -
