1. What's the first thing you do when factoring a quadratic equation like ax² + bx + c = 0 (where a is bigger than 1) using the box method?
2. When you're factoring ax² + bx + c = 0 with the box method, why do you need to find two numbers that multiply to a times c, and add up to b?
3. Use the box method to factor this: 2x² + 7x + 3. Show all the steps.
