Question

What is the product of 6+5i and 4+7i?

2 Answer

  • (6 + 5i)(4 + 7i) = 24 + 42i + 20i + 35i²
    = 35i² + 62i + 24

    The product of 6+5i and 4+7i is 35i² + 62i + 24.
  • Answer:

    -11+62i

    Step-by-step explanation:

    (6+5i)(4+7i)

    Use the Distributive Property

    24 + 42i + 20i + 35i²

    Combine like terms

    24+62i+35i^2

    i^2 = -1

    24+62i+35(-1)

    24+62i+(-35)

    24+(-35)= -11

    -11+62i
