Key Concepts
- A linear equation ax + b = 0 has one solution when a ≠ 0.
- Quadratic equations may have 0, 1, or 2 real roots depending on the discriminant.
- Matrix multiplication is not commutative: AB ≠ BA in general.
- The absolute value |x| measures distance from zero on the number line.
- Complex numbers extend reals with i where i² = −1.
Common Mistakes
- Sign errors when distributing negatives
- Dividing both sides by an expression that could be zero
- Losing solutions when squaring both sides
- Matrix dimension mismatch in multiplication
Frequently Asked Questions
Use the Quadratic Equation Calculator with a, b, c coefficients. It applies the quadratic formula and reports the discriminant.
Determinants indicate whether a matrix is invertible and are used in solving linear systems via Cramer's rule.
