🎯 Goal
Learn to combine like radicals by addition and subtraction.
📖 Lesson Description
- Only like radicals (same radicand) can be added or subtracted
- Example: \( 3\sqrt{2} + 5\sqrt{2} = 8\sqrt{2} \)
- Different radicands cannot be combined: \( \sqrt{2} + \sqrt{3} \) stays as is
âœï¸ Practice
- Compute \( 4\sqrt{5} + 7\sqrt{5} \)
- Compute \( 6\sqrt{3} - 2\sqrt{3} \)
- Compute \( 3\sqrt{2} + 5\sqrt{7} \)
