Text Solution

AI Generated Solution

To express the complex number \(\frac{(1+i)^2}{3-i}\) in the standard form \(a + ib\), we will follow these steps: ### Step 1: Expand the numerator We start with the numerator \((1+i)^2\). Using the formula for the square of a binomial, \((a+b)^2 = a^2 + 2ab + b^2\), we have: \[ (1+i)^2 = 1^2 + 2 \cdot 1 \cdot i + i^2 \] ...
