Questions & Step-by-Step Solutions

For the quadratic equation x^2 + 4x + 4 = 0, what is the nature of the roots?
  • Step 1: Identify the coefficients in the quadratic equation x^2 + 4x + 4 = 0. Here, a = 1, b = 4, and c = 4.
  • Step 2: Use the formula for the discriminant, which is b^2 - 4ac.
  • Step 3: Calculate b^2: 4^2 = 16.
  • Step 4: Calculate 4ac: 4 * 1 * 4 = 16.
  • Step 5: Subtract the two results: 16 - 16 = 0.
  • Step 6: Interpret the result: Since the discriminant is 0, this means the roots are real and equal.
  • Quadratic Equation – A polynomial equation of the form ax^2 + bx + c = 0, where a, b, and c are constants.
  • Discriminant – A value calculated from the coefficients of a quadratic equation (b^2 - 4ac) that determines the nature of the roots.
  • Nature of Roots – The classification of the roots of a quadratic equation as real and distinct, real and equal, or complex.
