Algebra II Start
Build a strong foundation in advanced algebra with polynomial operations, radical expressions, and essential problem-solving skills for SAT and ACT success.
What You'll Learn
- Add, subtract, and multiply polynomials using FOIL and distribution
- Expand binomials and recognize special patterns (difference of squares, perfect square trinomials)
- Simplify radical expressions by factoring out perfect squares
- Rationalize denominators containing radicals
- Apply polynomial and radical skills to real-world word problems
- Recognize and avoid common algebraic errors
Before You Start
Make sure you're comfortable with these prerequisite skills:
- Basic operations with exponents (x2 * x3 = x5)
- Combining like terms (3x + 5x = 8x)
- The distributive property: a(b + c) = ab + ac
- Perfect squares: 1, 4, 9, 16, 25, 36, 49, 64, 81, 100
- Order of operations (PEMDAS)
