Complete the Square
Welcome to the Completing the Square Tool! This is a step-by-step guide to help you learn how to complete the square for quadratic expressions and equations. Try it out below!
Example Walkthrough 🐸:
- Consider a quadratic expression of the form ax² + bx + c.
- Move the constant term to the other side: ax² + bx = -c.
- Divide the coefficient of x by 2, square it, and add to both sides.
- Factor the perfect square trinomial.
Here is a frog-themed example to start with: for 2x² + 8x - 3, your first step will be to isolate the x terms: 2x² + 8x = 3! Let's hop along from there!
