Questions & Step-by-Step Solutions

The quadratic equation x^2 - 4x + 4 = 0 can be expressed in which of the following forms? (2022)
  • Step 1: Start with the quadratic equation: x^2 - 4x + 4 = 0.
  • Step 2: Look for two numbers that multiply to 4 (the constant term) and add to -4 (the coefficient of x).
  • Step 3: The numbers -2 and -2 work because -2 * -2 = 4 and -2 + -2 = -4.
  • Step 4: Rewrite the equation using these numbers: (x - 2)(x - 2) = 0.
  • Step 5: Recognize that (x - 2)(x - 2) can be written as (x - 2)^2.
  • Step 6: Therefore, the quadratic equation can be expressed as (x - 2)^2 = 0.
