Study Guide — HSA.SSE.B.3
Choose and produce an equivalent form of an expression to reveal and…
Interpret and rewrite expressions using structure (factoring, completing the square).
What this standard means
- Factor a quadratic expression to reveal the zeros of the function it defines.
- Complete the square in a quadratic expression to reveal the maximum or minimum value of the function it defines.
- 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%.
- Apply choose and produce an equivalent form of an expression to reveal and… with models and explanation

Common mistakes
- Missing equivalent forms
- Incorrect factoring patterns
Review and practice tests
1. Start Review 1/10 when sets 1–3 feel comfortable. 2. Move up one review level with little help. 3. Use Practice Test 4/10–6/10 for mid-standard checks. 4. Practice Test 10/10 is the mastery bar for HSA.SSE.B.3.
- [ ] Identifies structure in expressions
