Circles & Quadratics: Center, Radius, Intercepts, Completing the Square | Paper Maximizing Area

Welcome back to tossinthetube!
In this lesson, I walk you step-by-step through solving algebra problems involving circle equations and quadratic models — exactly the type of problems students see in Algebra 2 and Precalculus.

📌 In this video, you’ll learn how to:
✔️ Rewrite a circle equation using completing the square
✔️ Identify the center and radius of a circle
✔️ Find x-intercepts and y-intercepts
✔️ Write the equation for the bottom half of a circle
✔️ Solve a real-world quadratic word problem (area of a printed page with borders)
✔️ Determine domain and range
✔️ Visualize and verify answers using a graphing calculator

This session mirrors a real tutoring lesson — clear explanations, written steps, and practical problem-solving strategies so you can follow along at your own pace.
