Why did the French Revolution happen?
Sage
The French Revolution (1789) had three main causes: financial crisis from war debt, social inequality under the Estates system where the Third Estate bore heavy taxes, and Enlightenment ideas about liberty and popular sovereignty.
The immediate trigger was a bread shortage — food prices spiked after crop failures, pushing the already-desperate commoners to revolt.

I don't understand how to factor trinomials like x² + 5x + 6
Sage
To factor x² + 5x + 6, find two numbers that multiply to 6 and add to 5. Those numbers are 2 and 3.
So x² + 5x + 6 = (x + 2)(x + 3) ✓
This is a common CLEP College Algebra topic — Unit 2: Algebraic Expressions.
