Question

Get me some help with it she of them

Answer 1

We are given the following expression:

`(6+4i)(9-11i)`

Using the distributive property:

`(6)(9)+(6)(-11i)+(4i)(9)+(4i)(-11i)`

Solving the products:

`54-66i+36i-44i^2`

Now we use the following property:

`i^2=-1`

Substituting:

`54-66i+36i+44`

Adding like terms:

`98-22i`

Since we can't simplify any further this is the answer.
