Chapter 8: Factoring - Exercises

Resolve the following expressions into their simplest factors:

  1. \(5a^2x - 10ax^2\)
  2. \(x^2 - 9y^2\)
  3. \(a^2 + 10a + 25\)
  4. \(x^2 - 7x + 12\)
  5. \(6a^2 - 5a - 6\)

Answer Key

  1. \(5ax(a - 2x)\)
  2. \((x - 3y)(x + 3y)\)
  3. \((a + 5)^2\) or \((a + 5)(a + 5)\)
  4. \((x - 3)(x - 4)\)
  5. \((2a - 3)(3a + 2)\)
