01 / QUICK RECAP
Connect the ideas.
- Collect exactly matching variable parts.
- Distribute to every term and preserve signs.
- Factorising reverses expansion; check the product.
- Bracket negative substituted values and attach units.
- Apply inverse operations to both sides when rearranging.
- Prove an identity algebraically; use one counterexample to disprove a universal claim.
