Factoring Quadratic Trinomial “𝑥^2 – 9𝑥𝑦 – 12𝑦^2” | Step-by-Step Algebra Solution - Math Doodle

This video will guide you through [How to Factor Quadratic Trinomial “𝑥^2 – 9𝑥𝑦 – 12𝑦^2”].

📌 How to Factor Trinomials of the Form 𝑥^2 + 𝑏𝑥𝑦 + 𝑐𝑦^2.
✓ Step 1. Write the factors as two binomials with first terms 𝑥 and last terms 𝑦 ➜ (𝑥 𝑦)(𝑥 𝑦).
✓ Step 2. Find two numbers 𝑚 and 𝑛 that
- Multiply to 𝑐 ➜ 𝑚• 𝑛 = c
- Add to 𝑏 ➜ 𝑚 + 𝑛 = 𝑏
✓ Step 3. Use 𝑚 and 𝑛 as the last terms of the factors ➜ (𝑥 + 𝑚𝑦)(𝑥 + 𝑛𝑦).
