QWhat is the quadratic formula?
Ax = (−b ± √(b² − 4ac)) / 2a
QExpand (a + b)²
Aa² + 2ab + b²
QWhat is the difference of squares factorization?
Aa² − b² = (a + b)(a − b)
QWhat does a negative exponent mean? (x⁻ⁿ)
A1/xⁿ — the reciprocal of the positive power
QWhat is the slope formula between two points?
Am = (y₂ − y₁) / (x₂ − x₁)
QWhat is slope-intercept form of a line?
Ay = mx + b
QWhat is x⁰ for any nonzero x?
A1
QSolve for x: 2x + 6 = 14
Ax = 4
QWhat does the discriminant (b² − 4ac) tell you?
AThe number of real solutions: positive → 2, zero → 1, negative → none
QWhat is xᵃ · xᵇ?
Axᵃ⁺ᵇ (add exponents when multiplying same bases)

- One fact per card. Card the formula and a tiny worked example separately — recognition of "when to use it" is the exam skill.
- Rate honestly. After each card, choose Again, Hard, Good, or Easy — the spaced repetition algorithm uses your answer to decide when the card returns, right before you'd forget it.
- A few minutes daily beats marathons. Ten new cards a day is roughly 3,650 a year, retained. Deep dives: Flashcards for programmers · How to make flashcards that actually work.
