Quadratics & Polynomials (Book 3.0)

Book 3 of The Calculus Bridge. You can read a graph — now learn to pull a curve's whole shape out of its formula alone.

Three short chapters:

• The Shape Hiding in the Formula: direction, width, vertex and axis of symmetry, straight from ax² + bx + c.
• Finding the Roots: factoring, the quadratic formula, and the discriminant that tells you how many solutions there are before you solve.
• Polynomials: More Twists, Same Logic: end behavior from the leading term, and whether a zero crosses the axis or just touches it.

Inside: a "Choose Your Move" checklist, a 20-problem practice set with full worked answers, and two short checkpoints — one before you read, one after — so you can see your own progress. Includes a page for parents and a page for teachers with standards notes.
