A quadratic equation is a type of algebraic equation where the highest power of the variable is 2. Examples: x2 - 11x + 28, 3x2 - 11x + 23 = 0, etc.
Real-Life Examples:
- The area of a square grows with its side: A = s2
- The stopping distance of a car increases with the square of speed: d ∝ v2
- The shape of a satellite dish is modeled by: y = x2
