Question

Use the foil method to find the terms of the following multiplication problem

Answer 1

Using the FOIL method, we must find the value of:

$(5+4i)\cdot(6-2i).$

Multiplying the terms, we get:

• First: 5 * 6 = 30

,

• Outside: 5 * (-2i ) = -10i

,

• Inside: 4i * 6 = 24i,

,

• Last: 4i * (-2i) = -8i² = 8.
