Reverberation is a phenomenon that occurs in enclosed spaces due to:

Reverberation is a phenomenon that occurs in enclosed spaces due to:

  1. Absorption of sound waves by the walls.
  2. Multiple reflections of sound waves within the space. ✓
  3. The Doppler effect caused by the listener’s movement.
  4. Cancellation of sound waves due to interference.

Explanation

Factorization expresses expression as product of factors. Common factor: 6x + 9 = 3(2x + 3). Difference of squares: a² – b² = (a+b)(a-b). Example: x² – 9 = (x+3)(x-3).

Quadratic factorization: x² + bx + c factors if you find two numbers multiplying to c and adding to b. x² + 5x + 6 = (x+2)(x+3) because 2×3 = 6 and 2+3 = 5.

For ax² + bx + c (a ≠ 1): multiply a×c, find factors adding to b, split middle term, factor by grouping. Or use formula. Factorization simplifies expressions and solves equations.
