Number and Quantity

The Real Number System
Extend the properties of exponents to rational exponents.
N-RN1 - Explain how the definition of the meaning of rational exponents follows from extending the properties of integer exponents to those values, allowing for a notation for radicals in terms of rational exponents. For example, we define 5^1/3 to be the cube root of 5 because we want (5^1/3)^3= 5^(1/3)^3 to hold, so (5^1/3)^3 must equal 5.
N-RN2 - Rewrite expressions involving radicals and rational exponents using the properties of exponents.
Use properties of rational and irrational numbers.
N-RN3 - Explain why the sum or product of two rational numbers is rational; that the sum of a rational number and an irrational number is irrational; and that the product of a nonzero rational number and an irrational number is irrational.
The Complex Number System
Perform arithmetic operations with complex numbers.
N-CN1 - Know there is a complex number i such that i^2 = -1, and every complex number has the form a + bi with a and b real.
N-CN2 - Use the relation i^2 = -1 and the commutative, associative, and distributive properties to add, subtract, and multiply complex numbers.
Use complex numbers in polynomial identities and equations.
N-CN7 - Solve quadratic equations with real coefficients that have complex solutions.
N-CN8 - Extend polynomial identities to the complex numbers. For example, rewrite x^2 + 4 as (x + 2i)(x - 2i).

A-SSE2 - Use the structure of an expression to identify ways to rewrite it. For example, see x^4 - y^4 as (x^2)2 - (y^2)2, thus recognizing it as a difference of squares that can be factored as (x^2 - y^2)(x^2 + y^2).
Write expressions in equivalent forms to solve problems.

A-SSE3b - Complete the square in a quadratic expression to reveal the maximum or minimum value of the function it defines.
A-SSE3c - 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 ? 1.012^12t to reveal the approximate equivalent monthly interest rate if the annual rate is 15%.

A-REI4b - Solve quadratic equations by inspection (e.g., for x^2 = 49), taking square roots, completing the square, the quadratic formula, and factoring, as appropriate to the initial form of the equation. Recognize when the quadratic formula gives complex solutions and write them as a +/- bi for real numbers a and b.
Solve systems of equations.
A-REI7 - Solve a simple system consisting of a linear equation and a quadratic equation in two variables algebraically and graphically. For example, find the points of intersection between the line y = -3x and the circle x^2 + y^2 = 3.
