Express the following in the form of a+ib
`(2+i)(2-3i)(4-3i)`

Explanation

To express the product \((2+i)(2-3i)(4-3i)\) in the form \(a + ib\), we will follow these steps:

### Step 1: Multiply the first two complex numbers
We start by multiplying \((2+i)\) and \((2-3i)\).

\[ (2+i)(2-3i) = 2 \cdot 2 + 2 \cdot (-3i) + i \cdot 2 + i \cdot (-3i) \]
