HSA.SSE.A1b

Interpret complicated expressions by viewing one or more of their parts as a single entity. For example, interpret P(1+r)n as the product of P and a factor not depending on P.

HSA.SSE.A2

Use the structure of an expression to identify ways to rewrite it. For example, see x⁴ – y⁴ as (x²)² – (y²)², thus recognizing it as a difference of squares that can be factored as (x2 – y2)(x2 + y2).

HSA.SSE.B3

Choose and produce an equivalent form of an expression to reveal and explain properties of the quantity represented by the expression.*

HSA.SSE.B3a

Factor a quadratic expression to reveal the zeros of the function it defines.

HSA.SSE.B3b

Complete the square in a quadratic expression to reveal the maximum or minimum value of the function it defines.

HSA.SSE.B3c

Use the properties of exponents to transform expressions for exponential functions. For example the expression 1.15t can be rewritten as (1.151/12)12t ≈ 1.01212t to reveal the approximate equivalent monthly interest rate if the annual rate is 15%.

HSA.SSE.B4

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.*

HSA.REI.C5

Prove that, given a system of two equations in two variables, replacing one equation by the sum of that equation and a multiple of the other produces a system with the same solutions.

HSF.BF.A1

Write a function that describes a relationship between two quantities.*

HSA.REI.C6

Solve systems of linear equations exactly and approximately (e.g., with graphs), focusing on pairs of linear equations in two variables.

HSF.BF.A1a

Determine an explicit expression, a recursive process, or steps for calculation from a context.

HSA.APR.C4

Prove 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.
