Algebra 2: Multiplying Complex Numbers
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.Multiply: (-6 - 7i)(5 + 4i)
- 2.Multiply: (4 + 7i)(-3 + 6i)
- 3.Multiply: (6 + i)(7 + i)
- 4.Multiply: (-5 - 7i)(-3 + i)
- 5.Multiply: (-2 + 4i)(6 + i)
- 6.Multiply: (5 - 2i)(-1 + 3i)
- 7.Multiply the conjugate pair: (-7 - 3i)(-7 + 3i)
- 8.Multiply the conjugate pair: (-7 + 3i)(-7 - 3i)
