Basic Mathematics QUESTION #2859
Question 1
Solve: \(x^2 - 7x + 12 = 0\)
  • x = 3 and x = 4✔️
  • x = -3 and x = 4
  • x = 3 and x = -4
  • x = -3 and x = -4
Correct Answer Explanation
Factorizing: \(x^2 - 7x + 12 = (x-3)(x-4) = 0\). So \(x = 3\) or \(x = 4\). Check: \(3 \times 4 = 12\) ✓ and \(3 + 4 = 7\) ✓.
