Questions & Step-by-Step Solutions

What are the roots of the equation x^2 + 4x + 4 = 0?
  • Step 1: Start with the 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: This can also be written as (x + 2)^2 = 0.
  • Step 6: To find the roots, set x + 2 = 0.
  • Step 7: Solve for x: x = -2.
  • Step 8: Since (x + 2) is squared, the root x = -2 has a multiplicity of 2.
