Questions & Step-by-Step Solutions

Which of the following is the correct factorization of the quadratic expression x^2 - 5x + 6?
  • Step 1: Identify the quadratic expression, which is x^2 - 5x + 6.
  • Step 2: Look for two numbers that multiply to the constant term (6) and add up to the coefficient of the x term (-5).
  • Step 3: The two numbers that work are -2 and -3 because -2 * -3 = 6 and -2 + -3 = -5.
  • Step 4: Write the factors using these two numbers: (x - 2)(x - 3).
  • Step 5: Check your work by expanding (x - 2)(x - 3) to see if it equals the original expression.
