What are the roots of x² − 5x − 24 = 0?

  1. 8 and −3
  2. −8 and 3
  3. 6 and −4
  4. 12 and −2
Answer and explanation

Answer: A. 8 and −3

Explanation: x² − 5x − 24 = (x − 8)(x + 3), so x = 8 or x = −3.

Previous: Solve: 2x + 3y = 23 and 3x − y = 7. What is x + y? · Next: If α and β are the roots of 2x² − 7x + 3 = 0, what is α + β?
