Algebra 2 · Kaden

General review — topic titles are not in Schoology. The course lists section numbers only (2.1–2.5, 3.5–3.7, 4.4–4.9, and 5.1–5.3 / 5.6). These are standard Algebra 2 skills, not a claim about what any one section is named.

📅 What to practice, by section number

2.1–2.5, 3.5–3.7, 4.4–4.9 — earlier quiz skills to keep warm (those quizzes were the weak spots).
5.1–5.3 and 5.6 — quiz on the calendar Nov 19–20 (during the trip). 5.1 / 5.2 Practice is also due Tue Nov 17, 8:30 AM PT.
Ch. 5 Test — calendar Dec 3–4, the day after the trip ends.

➗ Simplifying radicals

Factor out a perfect square: √(a² · b) = a√b.

√50 = √(25 × 2) = √25 × √2 = 5√2

√72 = √(36 × 2) = 6√2

🧩 Factoring — difference of squares

a² − b² = (a − b)(a + b).

x² − 9 = x² − 3² = (x − 3)(x + 3)

x² − 16 = (x − 4)(x + 4)

📏 Exponent rules (quick)

xᵃ · xᵇ = xᵃ⁺ᵇ
xᵃ / xᵇ = xᵃ⁻ᵇ
(xᵃ)ᵇ = xᵃᵇ
x⁰ = 1 (x ≠ 0) · x⁻ⁿ = 1/xⁿ

(x³)(x⁵) = x⁸

(x²)³ = x⁶
