Mathematics — first biennium · Lesson
Like radicals combine like terms: keep the radicand and combine coefficients. Simplify radicals before deciding whether they are like.
Prerequisites: Simplifying radicals
Goal: Operate with like radicals and recognize valid reductions.
In this lesson: Operate with like radicals and recognize valid reductions.
How to proceed: Check that the radicals are like after simplification; then operate only on their coefficients.
You can already assume: Simplifying radicals.

ConceptStep separates what is required from what is recommended or useful as reinforcement. Only required prerequisites block your progress.
Relationships: solid line = required · dashed line = recommended · dotted line = reinforcement.
