Multiply each pair of complex numbers, using i² = -1 to simplify. Write each answer in the form a + bi (a conjugate pair multiplies to a real number).

  1. 1.
    Multiply: (-6 - 7i)(5 + 4i)
  2. 2.
    Multiply: (4 + 7i)(-3 + 6i)
  3. 3.
    Multiply: (6 + i)(7 + i)
  4. 4.
    Multiply: (-5 - 7i)(-3 + i)
  5. 5.
    Multiply: (-2 + 4i)(6 + i)
  6. 6.
    Multiply: (5 - 2i)(-1 + 3i)
  7. 7.
    Multiply the conjugate pair: (-7 - 3i)(-7 + 3i)
