Solve: `x^2-(7-i)x+(18-i)=0ov e rCdot`

Explanation

To solve the quadratic equation \( x^2 - (7 - i)x + (18 - i) = 0 \) over the complex numbers, we can use the quadratic formula:

\[ x = \frac{-b \pm \sqrt{b^2 - 4ac}}{2a} \]

### Step 1: Identify coefficients
From the equation \( x^2 - (7 - i)x + (18 - i) = 0 \), we can identify:
