ALGEBRA I & II

Algebra

The language of unknowns

Solve equations, graph lines, factor polynomials, and work fluently with exponents and logarithms — the foundation every later course is built on.

UNIT 1

Equations & Lines

  1. 1

    Solving Linear Equations

    Isolate the variable by doing the same thing to both sides — every time.

  2. 2

    Slope & Linear Functions

    Slope measures steepness; the y-intercept tells you where the line starts.

UNIT 2

Quadratics

  1. 3

    Factoring Quadratics

    Rewrite a quadratic as a product so you can read the roots straight off.

  2. 4

    The Quadratic Formula

    One formula that solves every quadratic — and tells you how many solutions exist.

UNIT 3

Exponents & Logarithms

  1. 5

    Exponents & Logarithms

    Logarithms answer the question: what power do I need?
