Questions & Step-by-Step Solutions

If x^2 + 2x + 1 = 0, what is the value of x?
  • Step 1: Start with the equation x^2 + 2x + 1 = 0.
  • Step 2: Recognize that the left side can be factored as (x + 1)(x + 1) or (x + 1)^2.
  • Step 3: Rewrite the equation as (x + 1)^2 = 0.
  • Step 4: To solve for x, take the square root of both sides: x + 1 = 0.
  • Step 5: Subtract 1 from both sides to isolate x: x = -1.
