Question

So I’m doing this assignment and got stuck on this question can someone help me out Simplify(3-4i)(1-i)

Answer 1

Recall that:

`i^2=-1.`

Applying the distributive property to the given expression we get:

`3*1+3*(-i)-4i*1-4i*(-i).`

Simplifying the above result we get:

`\begin{gathered} 3-3i-4i+4i^2=3-3i-4i-4 \\ =-1-7i. \end{gathered}`

Answer: Option A.
