Learn to factor quadratic expressions by arranging blocks into rectangles!
📚 How It Works
Factoring a quadratic expression means finding two binomial expressions that multiply together to give the original quadratic. With algebra blocks, we represent this visually by arranging blocks into a rectangle.
Block Types:
Red squares: positive x² terms
Purple squares: negative x² terms
Blue rectangles: positive x terms
Orange rectangles: negative x terms
Green squares: positive unit terms (+1)
Yellow squares: negative unit terms (-1)
🎯 Interactive Practice
